Eight prisoners serving life sentences at HMP Whitemoor have each received additional prison time following a violent ten-hour mutiny at the maximum-security jail in October 2022. The prisoners, who were already serving life sentences for murder or conspiracy to murder, seized control of a prison wing, built barricades, and armed themselves with improvised weapons. Sentences for the mutiny were handed down at Cambridge Crown Court in February 2026, adding a combined total of 20 years to the sentences of the eight men involved.

What Happened During the HMP Whitemoor Mutiny?

The mutiny began at noon on 7 October 2022, when a group of eight prisoners at HMP Whitemoor refused to return to their cells following the lunch period. The prisoners — all of whom were already serving life sentences — seized control of a spur on one of the wings, establishing their position by creating a series of physical obstacles to prevent prison staff from entering.

The prisoners sprayed oil, shower gel, shampoo and other substances on the floor to make the area too slippery for staff to walk on safely. They also overturned furniture to construct a barricade and fashioned weapons from improvised materials, including metal poles broken from tables and from kettles. When prison officers attempted to reason with the group, they retreated after being confronted with these weapons. The standoff lasted ten hours before a national prison response team — a specialist enforcement unit trained for exactly these situations — was deployed to the wing. Even then, the team met significant resistance when attempting to enter the barricaded area.

Who Were the Eight Prisoners?

All eight prisoners involved were already serving life sentences for murder or conspiracy to murder at the time of the mutiny. They are named as:

Rick-Champion Champion Musaba, aged 30, was found guilty of participating in a prison mutiny. Nicholas Bridge, aged 26, was also found guilty of participating in a prison mutiny. Irwin Constable, aged 25, was likewise found guilty of participating in a prison mutiny. The remaining five prisoners — Dior Diego Jackson (aged 27), Bradley Blundell (aged 26), Korie Hassan (aged 33), Jahliel Rose (aged 29), and Troy Muschett-Thomas (aged 25) — each pleaded guilty to the lesser charge of violent disorder.

Sentencing at Cambridge Crown Court

Sentences for the mutiny were handed down across a series of hearings at Cambridge Crown Court, with the final sentence passed on 26 February 2026. The additional custodial terms imposed on each prisoner are as follows. Rick-Champion Champion Musaba received four years. Nicholas Bridge received three years and six months. Irwin Constable also received three years and six months. Korie Hassan received three years and four months. Dior Diego Jackson received one year and nine months. Bradley Blundell received one year and six months. Troy Muschett-Thomas received one year and six months. Jahliel Rose received one year and four months.

Combined, the additional sentences total 20 years. Because all eight men are already serving life sentences, the additional time does not change their eventual eligibility for release in a straightforward way — the Parole Board will still need to assess their risk when they become eligible under their original sentences. However, the additional terms reflect the seriousness with which courts treat attempts to undermine prison security, and demonstrate that even prisoners already serving life terms will face further punishment for serious misconduct within custody.

About HMP Whitemoor

HMP Whitemoor is a Category A maximum-security prison located near the town of March in Cambridgeshire, England. It holds some of the most high-risk prisoners in the country, including individuals convicted of terrorism offences and multiple murders. As a dispersal prison, Whitemoor is one of a small number of establishments designed to absorb the most dangerous prisoners in the system, preventing any one jail from becoming too concentrated a security risk.

The prison has a history of serious incidents. A significant escape by four prisoners, including two IRA members, took place in 1994 and prompted major reviews of security at high-risk establishments. HMP Whitemoor continues to hold some of the most notorious convicted criminals in England and Wales.

Aftermath and Wider Context

The Whitemoor mutiny and the subsequent sentencing in 2026 highlight the ongoing challenges of managing extremely dangerous and already heavily sentenced prisoners within the UK prison estate. When prisoners are serving whole life or very long tariff sentences, conventional deterrents lose their force — the prospect of additional time carries less weight for someone who will not see release for decades, if at all.

The case also reflects the physical dangers faced by prison staff. Officers at Whitemoor retreated when confronted with weapons and a slippery, barricaded floor — a reminder of the risks that custody staff take on a daily basis. The deployment of a national response team underscores how seriously the incident was treated at the time. More broadly, the case comes at a time when the UK prison system is under significant strain, with chronic overcrowding and understaffing creating conditions in which disorder can more easily take hold. Information about support for prisoners and their families is available throughout this site.

Frequently Asked Questions

What happened at HMP Whitemoor in October 2022?

Eight life prisoners at HMP Whitemoor, a maximum-security jail near March in Cambridgeshire, staged a violent ten-hour mutiny on 7 October 2022. The prisoners refused to return to their cells, seized a wing, built barricades with overturned furniture, covered the floor with oil and other slippery substances, and armed themselves with improvised weapons. A national prison response team was called to end the standoff.

Who were the eight prisoners sentenced for the Whitemoor mutiny?

The eight prisoners are Rick-Champion Champion Musaba, Nicholas Bridge, Irwin Constable, Dior Diego Jackson, Bradley Blundell, Korie Hassan, Jahliel Rose, and Troy Muschett-Thomas. All were already serving life sentences for murder or conspiracy to murder at the time of the mutiny. Three were found guilty of participating in a prison mutiny and five pleaded guilty to violent disorder.

How much extra time did the Whitemoor prisoners receive?

The eight prisoners received additional sentences totalling 20 years between them. Individual sentences ranged from one year and four months to four years on top of their existing life sentences. The sentences were handed down at Cambridge Crown Court, with the final sentence passed on 26 February 2026.

Does extra prison time affect lifers already in custody?

Yes, but in a different way to how it affects prisoners on fixed-term sentences. For life prisoners, additional sentences mean they must serve more time before they can be considered for release by the Parole Board. It also forms part of the record that the Parole Board considers when assessing whether a prisoner is safe to release, so it can significantly affect long-term prospects even when the arithmetic impact on a minimum term is limited.

What is a prison mutiny charge in UK law?

In English law, prison mutiny is a specific offence under the Prison Security Act 1992. A person commits prison mutiny if they take part in a concerted act of indiscipline by two or more prisoners that is intended to further an illegal purpose, to further a common purpose that is not illegal, or that appears to an officer to be a threat to the good order or discipline of the prison. It carries a maximum penalty of ten years imprisonment. Violent disorder is a separate offence under the Public Order Act 1986 and carries a maximum of five years.
