Police Admit Errors In Sydney Rapist Case

Police admit they made "errors" in handling a complaint about a convicted rapist weeks before he allegedly sexually assaulted a seven-year-old girl at a southern Sydney dance studio.

NSW Police Commissioner Mick Fuller on Thursday said an internal investigation revealed a woman reported an offensive call from Anthony Sampieri -- who was on parole for a serious sexual assault -- to an officer at St George Police Station on October 26.

But the parole board was not told of the breach, which could have seen his parole revoked, sending him back to jail.

A few weeks later he allegedly physically and sexually assaulted a seven-year-old girl in the toilet of a dance studio in Kogarah and stabbed a man who confronted him.

He remains under guard in hospital.

"At best an officer or the organisation potentially has failed to notify the parole board of a potential parole breach, and at worst an officer has neglected their duty to a victim of NSW," Fuller told reporters in Sydney.
