An attack on prison staff by two inmates with bladed weapons is being treated as a terror attack, the Metropolitan Police has confirmed.
Four officers and a nurse were injured at HMP Whitemoor in March, Cambridgeshire, on Thursday.
One attacker is understood to be Brusthom Ziamani, 24, found guilty of preparing an act of terrorism in 2015.
All five staff have since been released from hospital and the Met’s Counter Terrorism Command is investigating.
One officer at the maximum security jail sustained serious stab injuries to his head, face and back when he was attacked from behind by the two inmates wearing fake suicide belts and using improvised weapons, POA general secretary Steve Gillan said.
“There is no doubt in my mind that but for the bravery of staff, then this morning we could have been talking about a death of a prison officer at Whitemoor Prison,” he added.
