At a youth detention centre in north-east England, the paedophile Neville Husband raped and assaulted countless boys. Why was his reign of terror allowed to go on – and why hasn’t there been a public inquiry?

When I met Kevin Young in 2012 he was in his early 50s, handsome, charismatic, smart – and utterly broken. The moment he started talking about Medomsley detention centre he was in tears.

Young was born in Newcastle, in 1959. At two, he was taken into care, and his parents were convicted of wilful neglect. At eight, at a school in Devon, he was sexually abused by the gardener. At 14, at St Camillus, a Catholic residential school in Yorkshire, he was sexually assaulted by the headteacher, James Bernard Littlewood. But none of this compared with his experience at Medomsley, a youth detention centre in north-east England.
