Boys school a 'candy shop' - inquiry

A man who was abused by a pedophile at Sydney's prestigious Knox Grammar School said he was surprised to discover the teacher was still employed there 15 years later.

In a statement read to a royal commission hearing on Monday, Matthew O'Neal, who was abused by music teacher Barrie Stewart, said when his brother started at the school in 1990, Stewart was still there.

"A gay pedophile in a boys school is like a kid in a candy shop. He should never have been working there," Mr O'Neal said.
