At the point Gabriella Jaiyesimi began fitting while she was in the store, it was coincidence that one Tesco employee had personal experience of seizures, recognised these in Ms Jaiyesimi and was able to describe them to ambulance control. That individual then did as she was trained to do and left the management of the situation to the duty manager.

When Ms Jaiyesimi was on the floor having suffered several fits, no person put her in the recovery position. They were apparently unaware that her present position could be causing an airway obstruction preventing her breathing.

Then when Ms Jaiyesimi stopped breathing, nobody recognised this, though they were looking at her and made one inadequate attempt to feel for breathing (by placing a single finger somewhere near her nose).

No person ever attempted to check Ms Jaiyesimi’s pulse to see if her heart was still beating.

Even if they had identified her cardiac arrest, there was nobody present who would have started CPR. Nobody thought of fetching one of the store defibrillators. Lack of CPR notwithstanding, the failure to understand the situation properly meant that nobody relayed the crucial information of the arrest to the ambulance service.

It is impossible to say whether, if effective first aid and CPR had been administered, Ms Jaiyesimi’s life could have been saved. However, it is surely in the public interest that at least basic first aid can be offered to shoppers as well as to staff, and I heard that Tesco is committed to looking after its shoppers. When Gabriella Jaiyesimi suffered a cardiac arrest –

Tesco

1. There was no Tesco first aider working at Colney Hatch.

2. The TSS security officer was first aid trained, but none of the Tesco staff knew that.

3. All staff, including the TSS security officer, properly understood the Tesco policy of calling the duty manager to assess such an emergency and decide upon the correct course of action, but the duty manager charged with this responsibility had no CPR or first aid training. She told me that most of the Tesco duty managers were not CPR or first aid trained.

She did call the ambulance service, but she was not in a position to make a properly informed decision as to how to proceed at scene. She tried to follow the instructions of ambulance control, but she had no context for this and was not able to follow these instructions fully.

I heard that it was the duty manager’s choice not to be first aid trained. She said that she did not like blood and was afraid of the responsibility of a paramedic. However, on further exploration she said that she would like to be able to recognise a person not breathing and she would like to be able to administer basic first aid.

TSS

4. The TSS security officer was first aid trained, but did not tell anyone that he was first aid trained.

He told me repeatedly that his job was simply to do whatever the duty manager told him to do. Despite being the only first aider present, he took no responsibility at scene. He failed to offer Ms Jaiyesimi or the duty manager any meaningful support at all.

The SIA

The security officer had undergone SIA compliant first aid training in order to renew his licence. His first aid at work qualification was in date. He told me that his role as a security officer was to ensure the safety and security of people and merchandise in the store.

5. However, he did not display any understanding of basic first aid procedures. He told me that the first aid training he had received was simply a tick box exercise to enable him to renew his SIA licence.
• When the duty manager specifically asked him to check for breathing, his one attempt to do this was wholly ineffective.

• He never considered checking for a pulse. He told me that he had never been trained to check for a pulse.

• He said that he had not been trained in how to use a defibrillator and so he would not consider fetching one.

• When the staff member on the phone to the ambulance service relayed the instruction to place Ms Jaiyesimi in the recovery position, he did not. He told me that he did not remember being asked to do this. He also told me that he did not remember ever being taught the recovery position.

• Finally, the security officer said that if he did ever see anyone not breathing in the future, he would wait for the arrival of paramedics to attempt to do anything about that.

Dear Madam

Inquest touching the death of Gabriella Jaiyesimi

Thank you for your Regulation 28 Report dated 26 August 2025, issued following the inquest into the death of Gabriella Jaiyesimi.

We write on behalf of T.S.S (Total Security Services) Limited (T.S.S) in response to your Regulation 28 Report.

Within the report you raise a number of matters of concern. We have adopted your numbering to respond in relation to the specific concern directed to T.S.S:

4. The T.S.S security officer was first aid trained, but did not tell anyone that he was first aid trained. He told [you] repeatedly that his job was simply to do whatever the duty manager told him to do. Despite being the only first aider present, he took no responsibility at scene. He failed to offer Ms Jaiyesimi or the duty manager any meaningful support at all.

Response

T.S.S recognises the importance of the concern raised and has carefully considered the specific circumstances revealed by the evidence presented by its security officer who attended Ms Jaiyesimi.

T.S.S only employs officers who hold a valid SIA licence. This is a permit issued by the Security Industry Authority (SIA) to perform licensable activities in the UK’s private security industry.

The licence ensures that officers have received training and are prepared to perform their duties. In order to obtain a licence, officers must attend an SIA-endorsed training course.

Since April 2021, the SIA has made it a legal requirement that all persons enrolling on a Door Supervisor or Security Officer course must hold a valid Emergency First Aid at Work qualification or equivalent. The SIA will not allow officers to complete courses without evidence of a valid Emergency First Aid at Work qualification.

Date: 20 October 2025

As the SIA regulates the requirements of the first aid course towards its accreditation, T.S.S does not have any authority to view or assess the validity of the Emergency First Aid at Work qualification. However, to satisfy itself, T.S.S conducts a monthly audit to ensure that all its employees continue to hold valid licences that have neither been revoked nor expired.

Regarding the relationship between Tesco PLC and T.S.S security officers, we consider it important to clarify that the security officer was not employed as a first-aider and there has never been, nor is there currently, a contractual requirement by Tesco PLC for T.S.S security officers to provide first aid to Tesco employees or members of the public in Tesco stores. This is on the basis that Tesco has its own provision for first-aiders within its stores who are called to any medical emergency. There are no current T.S.S employees who hold a role as a Tesco first-aider.

In the event of a medical emergency, T.S.S expects all its employees to follow their SIA licence training. This includes, when required, assisting emergency services and following any instructions provided.

Almost all of T.S.S’s officers obtain their own licences by attending training courses provided by third-party SIA-endorsed providers. As this is a matter regulated by the SIA, T.S.S does not control where or how officers complete their training. The security officer involved in this incident completed his SIA licence training through the third-party SIA-endorsed awarding organisation, Pearson, on 24 June 2023. T.S.S had no involvement in his first aid training. We trust this information is of assistance and provides reassurance regarding the extent of the action T.S.S. is able to take. As we know that you will share this response with Ms Jaiyesimi’s family, T.S.S would like to express its sincere condolences for their loss.

Dear Coroner, Tesco Stores Limited Tesco House Shire Park, Kestrel Way Welwyn Garden City AL7 1GA 21 October 2025 RE: Regulation 28: Report to Prevent Future Deaths – Gabriella Omolabake Torisheju JAIYESIMI (Deceased) We refer to the Regulation 28 Report for the Prevention of Future Deaths, dated 26 August 2025 (the “PFD Report”). We note that the PFD Report was issued to the Chief Executive of Tesco Plc, although the interested party at the Inquest to which the PFD Report relates was Tesco Stores Limited (“TSL”). TSL is the relevant UK trading entity of the Tesco group of companies, and it is that entity which therefore provides this response.
1.
2. I.
3. I am , Group & UK People Safety Director for Tesco Plc, the parent company of TSL. TSL is the UK trading entity of Tesco Plc, which owns and operates its retail stores throughout the UK. I have held this position since July 2018, having worked for Tesco since 2009 in a number of health & safety related management roles in the UK and across the Tesco Group. I am authorised to respond on behalf of TSL. May I first take this opportunity to express my personal condolences and, on their behalf, to repeat those of the senior leadership team and colleagues at TSL, to Ms Jaiyesimi’s family. Coroner’s concerns We note the matters giving rise to your concerns in Section 5 of the PFD Report. We note specifically in relation to TSL, that you identify that the TSL colleagues who attended to Ms Jaiyesimi (who were not trained first aiders) lacked sufficient understanding of 1

Docusign Envelope ID: 84E1A8D0-B677-4816-98EB-8E9FDE9E816D Ms Jaiyesimi’s then medical situation to relay relevant information to Ambulance Control, so that effective first aid (as directed by Ambulance Control) could be rendered pending arrival of paramedics. You conclude “it is surely in the public interest that at least basic first aid can be offered to shoppers as well as to staff, and I heard that Tesco is committed to looking after its shoppers.”
4.
5. II. At Tesco we care about the health and safety of our colleagues, customers and anyone else impacted by our businesses. It is at the heart of how we do business and our guiding principle in everything Tesco does is “Everyone, Every day, Home safely”. This applies as much to our customers and visitors (non-employees) as it does to our colleagues (employees). We are always, as a business and as individuals, extremely sorry to hear of any incident occurring in our stores where the outcome is serious, as in these tragic circumstances. Whilst we regularly review our systems and procedures to ensure safety, we welcome the opportunity to consider whether we can do more, as we have done since becoming aware of the incident and following receipt of your PFD Report. The Regulatory Framework III.
8.
9.
10. Provision of first aid in Tesco stores In our retail stores, we have first aid trained colleagues who may provide treatment or assistance, as required, to colleagues, customers or visitors. There is no requirement, or indeed necessity, for all colleagues to be first aid trained, and as you identified in your PFD Report, this means that some colleagues may not be in aposition to understand how to respond to a medical incident in terms of a first aid response. Store colleagues will, however, through their training, know to call for a Duty Manager and a trained first aider, as the evidence in the Inquest demonstrated. 2
6. The Health and Safety (First-Aid) Regulations 1981 (the “Regulations”) provide the relevant regulatory framework for the provision of first aid by businesses such as TSL. The Regulations do not require employers to provide first aid for anyone other than their own employees and there is no legal duty on employers to make first aid provision for non- employees such as the public, as confirmed by paragraph 28 of the Health and Safety Executive’s (HSE) Guidance on the Regulations (L74) (the “Guidance”).
7. Notwithstanding the absence of any legal duty to provide first aid to non-employees, paragraph 28 of the Guidance also acknowledges that “many organisations, such as schools, places of entertainment, fairgrounds and shops, provide a service for others and it is strongly recommended that employers include non-employees in their assessment of first-aid needs and make provision for them”.

Docusign Envelope ID: 84E1A8D0-B677-4816-98EB-8E9FDE9E816D
11. In the majority of cases our trained first aiders will respond promptly to incidents, but on a small number of occasions (and as was the case here), if a first aider is unexpectedly unavailable, colleagues without first aid training may be required to attend to manage the situation and liaise with Ambulance Control if required. (A situation which is recognised and provided for by the Regulations, and recognised by the HSE as the role of an “Appointed Person”.) In all cases, it is Tesco’s policy that a store’s duty manager (being
12.
13. the team or lead manager who is on duty for a particular shift) attends all incidents in a store (even if a first aider is present). In light of your remarks at the Inquest and as set out in the PFD Report, we have identified an opportunity to deliver additional training to our store management teams (including shift leaders, team managers, lead managers and store managers - i.e., those who will perform the role of duty manager from time to time and may, therefore, be required to perform the role of an Appointed Person). We will be delivering internal “Appointed Person” training to c. 30,000 UK store management colleagues, commencing 1 December 2025, with a proposed completion date of 28 February 2026. This training will ensure managers have the requisite skills to provide information to, and follow the instructions of, Ambulance Control and administer basic first aid when specifically directed by the call operator (we note that the HSE is clear in its guidance that those who are not first aid trained, including Appointed Persons, should not attempt to render first aid). This is mandatory training that store management colleagues will be required to complete. It is hoped that this both reassures you that we have taken steps to address your concerns and also provides reassurance to our customers of TSL’s commitment to having in place adequate arrangements to properly assist with first aid incidents when required. We also recognise, as you did during the Inquest, that our store colleagues who assisted Ms Jaiyesimi tried their best in difficult circumstances and we hope this new training better supports them in the future.

REGULATION 28: REPORT TO PREVENT FUTURE DEATHS IN THE MATTER OF MISS GABRIELLA JAIYESIMI We are writing in response to the Prevention of Future Deaths Report regarding the death of Gabriella Omolabake Torisheju Jaiyesimi, addressed to Tesco PLC, Total Security Services Limited (“TSS”), a security company and the Security Industry Authority (“SIA”). This response comprises the formal response of the SIA to that report. We extend our deepest sympathies to the family of Gabriella Omolabake Torisheju Jaiyesimi, whose sad death in February 2025 was the subject of the coroner's inquest. On receipt of the Prevention of Future Death Report on Friday, 29 August 2025 we were made aware of the involvement of a security operative in these proceedings. On 24 September 2025 we obtained and subsequently listened to the recording of the inquest proceedings to fully understand the circumstances. We welcome the opportunity to respond to the matters that you have raised in the Report relating to the conduct of the security operative, as set out at paragraph 5 of your Prevention of Future Death Report under the heading ‘the SIA’. Recognising that the SIA was not called as a professional witness or listed as an Interested Person, we have set out an explanation of the role of the SIA, and details of the existing standards of training and expectations of security operatives that apply and are relevant in this matter. We then address in turn the matters listed for the SIA’s attention and explain what actions we have taken or asked others to take, where it is their responsibility. Background Information
1. The Security Industry Authority (“SIA”) is responsible for the licensing of the private security industry in the United Kingdom. It was established by the Private Security Industry Act 2001 (“the Act”).
2. Individuals who undertake ‘manned guarding’ (the term used in the legislation) are one of the types of persons who are required to hold an SIA licence. Manned guarding includes security guarding, door supervision, close protection, guarding cash and valuables in transit and public space surveillance using CCTV. Where an individual carries out licensable conduct, they are committing an offence of engaging in licensable conduct without a licence.
3. Where security guarding activities are performed by an operative contracted by a business from a security provider, then that individual needs to have a security guarding licence. This is the situation in retail settings such as Tesco.

4. The door supervision licence also allows security operatives to perform the activities of a “security guard”, or a separate licence is required to carry out that activity. The nature of the employment in private security
5. A security officer can be employed in several ways: directly by the premises owner or operator, through a contracted security company, or on a temporary basis at various locations to fill short- term or last-minute vacancies, with or without the use of labour providers. As such the SIA’s role is not to record where security operatives are working and it can never know where, or for whom, an individual security operative is working. Similarly the SIA will never know the specific nature of activity they are deployed for or the setting an operative will be working in, or the risks associated with an individual’s deployment. The Role of the SIA
6. The SIA has been in operation since 1 April 2003.1 The functions of the SIA are set out in section 1(2) of the Act. They include responsibility for licensing individuals who are undertaking the regulated activities of a security operative and for setting and approving standards of conduct and training.
7. The regulatory regime which is operated by the SIA is UK-wide.
8. The legislation requires the licensing of individuals by the SIA, not the security businesses. However, the SIA is also authorised to run, a voluntary quality scheme for security businesses, called the “approved contractor scheme”. TSS is a member of that scheme. The licensing criteria
9. The purpose of licensing individuals is to ensure at the time they apply for or renew a licence, usually every three years, the individual is fit and proper to hold it, having met criteria and obtained the relevant entry level qualifications. That knowledge and skill is confirmed as met through the security operative having obtained the relevant licence-linked qualification for the sector that they intend to work in. The qualifications are provided, approved and regulated by other bodies.
10. To qualify for a licence to work in any front-line licensable activity, an applicant must:
• be aged 18 or over
• pass an identity check
• pass a criminal record check
• have the right to work in the UK; and
• have the appropriate and relevant, licence-linked qualification.

1 The Private Security Industry Act 2001 (Commencement No. 1) Order 2002

11. The licence currently costs the applicant £184 and is valid for 3 years. Further details of the licensing criteria and how the SIA assesses and licenses an individual as well as the criteria for renewal of the licence are set out in the SIA publication Get Licensed. A copy of the current Get Licensed criteria (version February 2025) is attached to this response as SIA/1.
12. Other ‘Information’ may be taken into account as set out in Get Licensed at page 63 either as part of applying for a licence or during the period of the licence if it suggests the person may not be a fit and proper person to hold or continue to hold a licence. If there are serious concerns that a threat to public safety could exist or if it is otherwise in the public interest to do so, the SIA has the power to suspend a licence that has been granted under s10 of the Act to allow us time to look into an issue and make a decision on whether the licence holder should continue to hold a licence. If the SIA decides that it is necessary to suspend someone’s licence it will write to them. The licence holder will be invited to make representations before a decision is taken to revoke their licence. The licence holder has a right of appeal to the Magistrates Court and has 21 days to exercise this right of appeal. Explanation of the Existing Regulatory Standards Set - Qualifications and Training Requirements
13. The SIA’s role is to set and/or approve standards which set out the skills and knowledge that security operatives require.
14. It does so by creating and publishing “Specifications for Learning and Qualifications”. The SIA reviews the specification requirements every five years. These specifications are used as the basis for qualifications and associated assessments, by awarding organisations such as Highfield Qualifications, Laser Learning Awards, Pearson, Qualifications Network, SFJ Awards and other approved awarding organisations. These awarding organisations, who are themselves regulated, take the specifications and make them into nationally recognised qualifications. They also approve and monitor training providers who deliver the training and assessment.
15. Using government regulated qualifications is a well-established model that is used in numerous other sectors in the UK. Regulation of qualifications required for a licence or licence renewal is the Office of the Qualifications and Examinations Regulator, OfQual in England, Wales and Northern Ireland and Scottish Qualifications Authority, SQA in Scotland. They approve and regulate Independent Awarding Organisations responsible for creating, overseeing and awarding the qualifications obtained. The Awarding Organisations in turn, approve individual training providers and centres.
16. There are over 650 training providers approved by the Awarding Organisations to deliver SIA licence linked qualifications across the UK. There is no government training inspectorate for adult education (Ofsted’s remit and reach does not extend to this) so this falls to a combination of the supervision by the qualifications regulators and oversight, monitoring and auditing by the Awarding Organisations over the training providers. In this case the relevant Awarding Organisation is Pearson.
17. The qualification content provides for entry level knowledge. Once an SIA licence has been obtained, it is the employer's responsibility to provide ongoing professional training, job-specific development, and to ensure that each operative is properly briefed and supported in their specific deployment.

The Introduction of First-Aid Training Requirements for Licences
18. In April 2021 the SIA imposed a new requirement that before attending training leading to a licence linked qualification for Door Supervision or Security Guarding, an individual needed to present evidence that they were competent in First Aid or Emergency First Aid at Work. This extended to individuals as a pre-requisite to the training required before an individual could renew a licence. Later in the year the SIA also required individuals seeking to renew a Door Supervision or Security Guarding licence, to present a valid first aid certificate as a pre-requisite to their top up or refresher training.

19. The rules surrounding first aid certificates are set out by the Health and Safety Executive (“HSE”) ad have to meet the requirements of the Health and Safety (First Aid) Regulations 1981. This is usually achieved by the training centres being required to confirm to the Awarding Organisation that each learner was sufficiently qualified in First Aid or Emergency First Aid at Work. Sometimes the first aid course is included as an extra day in the security training. Alternatively, learners can arrange their own first aid training and certificate, or they may already have a valid one that meets the requirements.
20. Learners must present a current relevant first aid qualification certificate that is valid at the time of taking the training for at least a further 12 months, before they are able to take licence linked training for either a first time or refresher course. The SIA expects licence holders to keep their first aid certificates up to date.
21. A training centre should only accept a first aid qualification from a learner if all the following statements are true:
• It meets the requirements of Appendix 2, ‘Content of an emergency first aid at work (EFAW) course’ of Selecting a first-aid training provider: A guide for employers.
• It is valid for at least another 12 months from the start of the licence-linked training.
• The trainer has made reasonable efforts to confirm that it complies with all other requirements of Selecting a first-aid training provider: A guide for employers, particularly those listed in paragraph 14.
• They have made reasonable efforts to confirm that the practical elements of training were delivered and assessed face to face.
22. I attach as SIA/2 a copy of the HSE First aid at work: The Health and Safety (First-Aid) Regulations 1981, Guide on Regulations. Appendix 6, page 36 details the minimum training content required for a L2 Emergency First Aid at Work qualification. On completion of training, successful candidates should be able to:

• understand the role of the first-aider, including reference to: the importance of preventing cross infection;

• the need for recording incidents and actions;
• use of available equipment;
• assess the situation and circumstances in order to act safely, promptly and effectively in an emergency;
• administer first aid to a casualty who is unconscious (including seizure);
• administer cardiopulmonary resuscitation and use an automated external defibrillator;
• administer first aid to a casualty who is choking;
• administer first aid to a casualty who is wounded and bleeding;
• administer first aid to a casualty who is suffering from shock;
• provide appropriate first aid for minor injuries (including small cuts, grazes and bruises, minor burns and scalds, small splinters).

23. The first aid requirements are not a tick box exercise and were introduced as it was felt that there was a reasonable expectation by the public that security operatives would help during first aid emergencies.

24. From October 2024 the SIA required first aid courses to explicitly cover how to respond to life- threatening bleeding.

Action taken following receipt of the Prevention of Future Death Report
25. The SIA’s specialist team that carries out the work on setting the requirements and standards for qualifications has considered the Prevention of Future Death Report and has been provided with a briefing on the audio recording of the inquest proceedings to understand further the context and concerns raised.
26. The SIA is of the view that the existing L2 Emergency First Aid at Work requirement contains appropriate content to equip a security operative with the skills required to administer emergency first aid. The current specification content includes training on dealing with someone who is potentially unconscious and having a seizure including:
• how to check for breathing and a pulse;
• how to use a defibrillator; and
• how to place someone in the recovery position.

27. The SIA is of the view that further changes to the specification requirements for licensed-linked qualifications are not necessary as the L2 Emergency First Aid at Work qualification already provides licence holders with the right level of first aid training to assist members of the public in an emergency. If the Coroner or Chief Coroner disagrees with this position, having read the additional information provided in this response, we would be happy to discuss further.
28. The SIA has gone on to consider whether or not in this particular case there is any regulatory action that we should take in respect of or Total Security Services Limited given the

circumstances that have been brought to our attention through the Prevention of Future Death Report.
29. The following actions have been taken in relation to:

41. The SIA wrote to the Chief Coroner on 30 April 2021 to set out its regulatory interest in inquests involving private security and the circumstances in which it would invite a Coroners Court to provide the SIA Interested Person status and/or provide other expert witness assistance if helpful in some cases.
42. We will make contact with the current Chief Coroner to ask and offer this and work with her on how this might be more widely communicated to ensure we are able to assist the Coroner’s Court at and during relevant inquests in the future. The SIA’s expert leads in these areas would be happy to respond to any further queries or questions that arise as a result of this response.

Report sections

Investigation and inquest

On 25 February 2025, one of my assistant coroners, Sarah Bourke, commenced an investigation into the death of Gabriella Jaiyesimi. The investigation concluded at the end of the inquest on 22 August 2025. I made a narrative determination at inquest. I recorded the medical cause of death as:

1a hypoxic ischaemic brain injury 1b out of hospital cardiac arrest of uncertain aetiology

Circumstances of the death

Gabriella Jaiyesimi suffered seizures and a cardiac arrest on 24 January 2025 while at the supermarket Tesco in Colney Hatch. She died a month later as a consequence of the hypoxic brain injury she sustained during that cardiac arrest.

Before the arrival of an ambulance, she received no cardiopulmonary resuscitation (CPR) and no effective first aid at scene. Staff did call an ambulance.
