Death of 16-year-old at Feltham YOI sparks renewed calls to end child imprisonment

A 16-year-old boy has died after being found unresponsive at Feltham Young Offender Institution (YOI) in west London, prompting an investigation and renewed criticism of the UK’s use of custodial settings for children.

Emergency services were called to the facility shortly after 22:00 BST on Monday following reports of an “unwell child.” The teenager was treated at the scene and taken to hospital as a priority by the London Ambulance Service, where he later died. The Metropolitan Police said it was informed of the death in the early hours of Tuesday and is treating the case as “unexpected,” with inquiries ongoing. A post-mortem examination is due to take place.

The boy had been held at HMP Feltham A, which houses boys aged 15 to 18 who are on remand or serving custodial sentences. As with all deaths in custody, the Prisons and Probation Ombudsman will conduct an independent investigation.

In a statement, children’s rights charity Article 39 said it was “deeply saddened” by the boy’s death and extended its condolences to his family, loved ones, and other young people at the institution.

While the cause of death remains unknown, the organisation raised concerns about reports regarding the condition in which the boy was found, calling for these to be “urgently and transparently examined.”

The charity used the incident to highlight longstanding concerns about conditions within young offender institutions, describing Feltham as an establishment “plagued for years by the highest level of violence of any prison in the country.” It argued that the boy’s death should not be viewed in isolation, but as part of wider systemic failings.

“What we do know is that he was a child,” the statement said. “He hadn’t yet celebrated his 17th birthday and had his whole life ahead of him. He has now died in the care of the government.”

Article 39 reiterated its position that children should not be held in prison settings, arguing that such institutions are inherently unsafe and harmful. It cited a “wealth of evidence” showing that children in custody are exposed to trauma, inhumane conditions, and environments that can exacerbate the issues that led to their detention.

The charity called for a “full and independent investigation” into the death and urged the government to confront what it described as the broader implications of the case. It also renewed its demand for a clear, time-limited plan to end the use of young offender institutions and secure training centres for children, proposing instead smaller, welfare-based settings for those who cannot be safely managed in the community.

Immediate steps should be taken to close Feltham A, the organisation added.

The Youth Custody Service said it would be inappropriate to comment further while investigations are ongoing, but confirmed that its thoughts were with the boy’s family and friends.

The case is likely to intensify scrutiny of the youth custody system in England and Wales, particularly over the safety and welfare of children held in secure institutions.
