PARENTS of victims of a pedophile teacher at a Toowoomba Catholic primary school are calling for the Royal Commission into Institutional Responses to Child Sex Abuse to widen its probe to local police officers involved in the initial investigation.

At least three police officers who took statements in the 2008 investigation of the teacher later jailed for the rape and molestation of 13 girls had children who were students and either served on the Parents and Friends Association or whose spouses were senior staff at the school.
