Emergency services were called to HMP Belmarsh on Belmarsh Road, Thamesmead, on Saturday evening (12 October) after a fire broke out in the prison’s segregation unit.
Fire crews from the London Fire Brigade responded to the incident just after 5 pm, with multiple appliances on the scene to tackle the blaze. The affected area houses prisoners within the prison’s segregation unit, also known as the “punishment block.”
Reports suggest that several prisoners have been moved to a safe area while fire crews work to extinguish the flames and ensure the facility is secure.

The Ministry of Justice has been contacted for more information regarding the cause of the fire and the status of the evacuation, although further details are yet to be confirmed.
As of the latest update, there have been no reports of injuries, and the situation is being monitored closely by both prison officials and emergency responders.
