He now faces an even longer stay inside after brutally stabbing a prison officer at HMP Woodhill, near Milton Keynes, Bucks, in February 2021.

Tinling was being escorted to his cell after a workout when he attacked Samuel Morris.

He admitted attempted murder and is later convicted.

Tinling is housed in a special wing at Woodhill for extremely dangerous prisoners.

A spokesman for the Corrections Service said: “We will not tolerate attacks on our hard-working staff and always urge the highest possible punishment for those involved.”
