A former inmate told Newcastle Crown Court yesterday a prison officer at Medomsley Detention Centre in Consett, County Durham, had molested him in the locker room.
He said Neville Husband, now a United Reform Church minister, forced him to perform a sex act and left him terrified.
The attack, when he was a teenager, followed a series of incidents in the kitchen where Husband was in charge of catering, he claimed.
Husband, 65, of Snows Green Road, Shotley Bridge, denies 15 counts of indecent assault and one serious sex offence against six males aged 16 to 19 during the 1970s and 1980s. The trial continues.
