Evil child welfare boss, 78, who raped children in a dungeon at his young women's institution will spend the rest of his life behind bars

The former boss of a young women's institution who raped and abused girls and boys in the 1970s will spend the rest of his natural life behind bars.

In Campbelltown District Court on Friday, Frank Valentine, 78, was sentenced to 22 years behind bars, with a non-parole period of 13 years for 21 historical offences.

Valentine's reign of terror started in 1971, less than a month after arriving to work at a Western Sydney institution.
