Former teacher says he witnessed sexual assaults. St Stanislaus College, BATHURST

A FORMER school teacher has emerged as a key witness to the alleged sexual assaults of students, amid allegations that paint a picture of ''rampant pedophilia'' at St Stanislaus College in Bathurst.

The allegations, including that students were forced to have group sex and were hypnotised to have sex with teachers, were heard during a bail review for Brian Joseph Spillane, a former chaplain at the school.

Spillane, 66, is now facing 146 charges of indecent and sexual assault against 27 alleged victims after he was charged on Monday with 32 offences.
