A YOUTH worker who yesterday pleaded guilty in Wagga Local Court to 12 child pornography charges was caught after police found evidence of him boasting on the internet about assaulting children as young as seven.Police facts tendered to the court said 22-year-old Jacob Bennie was charged after police analysed the computer of another man and found various child pornography and child abuse material that was traced back to Bennie.The pornographic material consisted predominantly of written material saved on the man's computer during MSN chats, the facts said.They said Bennie had numerous on-line MSN contact with the other man as far back as July 25, 2005."During these conversations the accused and (the other man) openly discuss child sexual assaults," the facts said.Two of the offences depict sexual acts Bennie said he had committed upon children aged between seven and 15.Bennie, however, told police after he was arrested outside his Kilpatrick Street home on September 29 this year that none of the acts he had written about online were real, but were fiction from his fantasising."The accused informed police that he had a sickness and that he fantasised about sexual relations with children under 16 years of age," the police facts said.Bennie was employed as a part-time youth worker and was a third-year social sciences student at the time of his arrest.Magistrate Anthony Murray was quick to ask about Bennie's employment when he read the police facts."Has the place where he is working been notified of these offences?" Mr Murray asked. "It would be highly inappropriate if he was still working there."Bennie's solicitor, Chris Murnane, replied that Bennie was no longer working as a youth worker.Bennie pleaded guilty yesterday to six counts of disseminating/producing child pornography and six counts of using a carriage service to transmit child pornography.Mr Murray adjourned the case until December 14 to allow police time to give more details of the offences.According to police facts, Bennies' arrest came out of a police operation in the Lake Macquarie/Newcastle area called Strike Force Georgiana.Police there began investigations into pedophile activity in the Newcastle area in April, 2008.A man was arrested in October last year and was charged with 13 offences.According to police facts, a number of the computers were seized from the man's premises in Hamilton, Darlinghurst and Girvan. They were analysed this year and, according to police, contained various child pornography and child abuse material.
