Man dies in Croydon police custody; officer investigated

An investigation has been launched into the death of Jason Mattison, 52, who died while in police custody in Croydon. Mr Mattison was found unresponsive in his cell at the Windmill Road Custody Suite at approximately 1.30am on August 21. Custody staff and paramedics provided emergency first aid at the scene, but he was pronounced dead. A post-mortem examination has been conducted, with further tests pending to establish the cause of death.

Mr Mattison had been arrested on August 19 in Croydon. The arrest was made on a no-bail warrant issued by Croydon Magistrates’ Court after he failed to appear on charges of being drunk and disorderly. He remained in custody awaiting a court appearance.

Officer Subject to Investigation

The Independent Office for Police Conduct (IOPC) confirmed it is investigating the circumstances surrounding Mr Mattison's death. As part of its inquiry, the IOPC has served a notice of investigation on a designated detention officer. This officer is alleged to have failed to conduct a scheduled welfare check on Mr Mattison and to have incorrectly recorded that the check had taken place. The IOPC stated that Mr Mattison was subject to half-hourly welfare checks.

Amanda Rowe, IOPC director of engagement, expressed condolences to Mr Mattison's family. "This was a tragic incident in which a man has sadly died, and our thoughts are with Mr Mattison’s family and loved ones," Ms Rowe said, as reported by Your Local Guardian. "When someone dies in police custody, it’s important that a thorough and independent investigation is carried out to examine all the circumstances."

Ms Rowe added that the IOPC has met with Mr Mattison's family to explain its role and will keep them informed as the investigation progresses. Enquiries into the death are ongoing.
