A prison warden has been held hostage and stabbed in an attack by inmates believed to have been inspired by the Woolwich murder of Drummer Lee Rigby.

Three prisoners were reported to have held the warden hostage before stabbing him during a four-hour stand-off with guards on Sunday afternoon.

The attack at Full Sutton prison in East Yorkshire was said to have left the officer “badly shaken”, while a female prison guard was also understood to have been injured as she tried to intervene.

The incident reportedly took place after a prison imam called for inmates to pray for Drummer Rigby.

A source told The Sun: “This had all the hallmarks of a pre-planned attack inspired by the Woolwich atrocity. […]

Last year’s annual report on Full Sutton by the Independent Monitoring Board said the prison had seen an increase in Muslim prisoners and referred to “tensions between them and other prisoners.”

More than a fifth (22%) of the prison’s inmates in 2012 were Muslims.
