At 15, Gareth Myatt was small for his age – four foot ten and six-and-a-half stone. He was three days into a six-month sentence at Rainsbrook Secure Training Centre in Northamptonshire, run by G4S, for stealing a bottle of beer and assaulting a social worker at a children’s unit when he refused to clean a sandwich toaster in the dining area.
Two members of staff followed him to his room and began removing things. One of them tried to take away a piece of paper from the shelf, which contained his mother’s mobile phone number. He lunged at the staff member. The two members of staff, now joined by a third, restrained him.
