Police actions relating to a teenage boy’s arrest, welfare and disappearance prior to his death – British Transport Police and Metropolitan Police Service, September 2020

Investigation

On 30 August 2020, a 17-year-old was arrested by British Transport Police (BTP) officers following an incident at East Croydon Railway Station and taken to a Metropolitan Police Service (MPS) custody facility at Croydon. He was released from custody the following day and returned to his home address.

On 1 September, the teenage boy was reported missing after he had left his home address and the MPS began a missing person investigation. He was graded as a medium risk missing person. The following day, he was hit by a train at South Croydon train station and died.

On 2 September, we began an independent investigation after we received mandatory referrals from the British Transport Police (BTP) and the Metropolitan Police Service (MPS), as both forces had been in contact with the teenage boy in the days before his death.

Our investigation examined the steps taken to safeguard the teenage boy during his time in police custody, the police response after he had been reported missing and whether any police action caused or contributed to his death. We compared the decisions and actions taken by the police against local and national policies, procedures and legislation.

During our investigation we reviewed MPS and BTP documents in relation to arrest, detention in custody and missing person reports. We also took statements from officers and staff members from both police forces.

Our investigation concluded in August 2021. We waited for all external proceedings to be finalised before publishing our findings.

Our investigation found that no officer committed a criminal offence or behaved in a manner that would justify disciplinary proceedings.

We identified individual learning for officers serving with MPS and BTP.

We advised the performance of two MPS inspectors should be addressed. This related to the missing person investigation and failure to share information and to review outstanding missing persons investigations.  

We advised the MPS that it should also address the performance of three officers in custody, to remind them of the importance of adding accurate information to the custody log and of the appropriate level of detail to be included in risk assessments.

We advised BTP that it should address the performance of two officers involved in his arrest and subsequent criminal interview and remind them of their responsibility to complete safeguarding forms for vulnerable members of the public.

In March 2023, an inquest concluded that the teenage boy died by suicide.

The jury identified there were several factors that contributed to his death, which included a failure by social services to share information with the police regarding his vulnerabilities. Police forces also failed to adequately share risk information with each other and to complete a mental health assessment whilst he was in custody.      

We carefully considered whether there were any organisational learning opportunities arising from the investigation. We make learning recommendations to improve policing and public confidence in the police complaints system and prevent a recurrence of similar incidents.

In this case, the investigation identified areas of organisational learning.

We recommended BTP ensure their staff are aware of the necessity of completing appropriate safeguarding and risk assessment forms for vulnerable persons, after we found no safeguarding forms were completed for the teenage boy, even though he was vulnerable as a youth.

We used a different legislative power to issue a recommendation to the MPS. This requires the police service to respond to our learning with their acceptance and proposed resolution, if applicable.
