Prison staff feared their colleague, locked in a room and being attacked by crazed extremists, was facing the same gruesome death as murdered soldier Lee Rigby.
The terrified officer, in his 30s, was finally freed by a specialist riot squad who stormed the room where he was held for five hours and beaten mercilessly by the extremists, who told him he would die.
And the vicious assault was sparked by a simple call from a prison imam to pray for drummer Lee who was butchered in the street last week near his barracks in Woolwich, South East London.
The ringleader of the prison attack flew into a rage at the request, insisting the 25-year-old’s murder was justified.
Recruiting two fellow Muslims, an African-born fanatic and a British convert, they kidnapped the guard on Sunday and bundled him into a cleaning room at Full Sutton jail near York.
