Father of three dies at HMP Pentonville amongst known issues

An inquest has opened into the death of Gareth Chumber-Kelly, a 33 year old father of three who died just four days after prison authorities remanded him to HMP Pentonville.

The court had not convicted him of the offence of which it held him.

Gareth died on 17 July 2023 after taking his own life. It occurred during the most dangerous period of custody: the first days after arrival. Researchers and campaigners have documented this risk repeatedly.

An inspection from the Inspectorate of Prisons found that prisoners at HMP Pentonville face “appalling treatment and conditions.” A shocking 44% of prisoners felt unsafe in the jail.

As a result, one question now dominates. Why did the state place him in a prison already known to be unsafe?

HMP Pentonville: four days was all it took

Gareth lived in Enfield. According to his family he was hardworking, loving and deeply devoted to his children. He enjoyed music, cars and technology.  Yet just four days after entering state custody, he was found dead from apparently self-inflicted means.

The inquest, which opened on 19 January 2026 at Bow Coroner’s Court, will examine how prison staff cared for and supervised Gareth. In addition, It will also consider whether agencies shared information properly, and whether staff identified and acted on any risks .

Courts ask these questions in many deaths in custody. However, at Pentonville, they carry particular weight.

This death was not unforeseeable

As mentioned above, inspectors who had examined Pentonville have repeatedly warned about serious failures at the facility. Most recently, in 2025, HM Inspectorate of Prisons issued an urgent notification warning of dangerous conditions.

Inspectors found people being held unlawfully beyond their release dates. They also found that new arrivals were receiving “wholly inadequate“ care.  Meanwhile, they recorded high number of self-inflicted deaths. Living conditions were described as squalid.

The state knew all of this. Nevertheless, it changed little.

Since Gareth’s death, at least ten more people have died at Pentonville. At least five of those took their own lives. These deaths form a pattern not a coincidence.

Remand prisoners face extreme risk

In law, the state presumes people on remand to be innocent. In practice, the prison system treats many of them as disposable.

Evidence consistently shows that the first days in custody carry the highest risk of suicide. Sudden imprisonment, separation from family, fear of the unknown, and limited access to mental health support combine to create a lethal mix.

In Gareth’s case, the system had days to intervene. It did not.

When someone dies this quickly, the failure is not rooted in hindsight but in prevention.

Oversight without consequence

Inspectors visited Pentonville. They issued warnings. They published reports. The prison continued to operate as normal. People continued to die.

Gareth’s death exposes the deeper problem. Oversight exists, but accountability does not. Authorities can formally declare a prison unsafe and still leave people inside it. Urgent notifications do not force immediate or meaningful change.

Under Article 2 of the European Convention on Human Rights, the state must take reasonable steps to protect the lives of people in its care when authorities know, or ought to know, of a real and immediate risk to life.

Families pay the price when the state fails to act.

What campaigners say

INQUEST, the organisation is supporting Gareth’s family, has long warned that deaths in prison are not isolated tragedies but the predictable outcome of unsafe systems.

Responding to recent prison safety statistics, INQUEST director Deborah Coles said record levels of self-harm and deaths reveal:

The inherent violence and harms of prison

Added to that, vulnerable people are being placed in environments that actively worsen stress rather than alleviate it.

The Howard League for Penal Reform has also repeatedly raised concerns about conditions at local prisons like Pentonville, particularly for people on remand. Following the publication of custody safety data, the charity warned that that prisons remain:

Unsafe and mired in distress and misery.

And, the publication argues that exposing people to despair and neglect does nothing to protect life or prevent future harm.

Campaigners have consistently stressed that early days in custody require heightened care, not isolation and indifference. Yet deaths continue to occur during precisely this period.

Presumed innocent, treated as disposable

Gareth Chamber-Kelly entered Pentonville presumed innocent. He left in a body bag. The question must be asked: why is HMP Pentonville allowed to operate under such dire conditions for inmates?

That is not a tragedy without cause. It is the foreseeable outcome of a prison system that continues to warehouse vulnerable people in institutions already known to be dangerous.

How many warnings does a prison need before deaths are treated as preventable? How many people must die on remand before the state accepts responsibility?

Gareth was not the first to die at Pentonville. There is a very real danger that he will not be the last.
