A Mt Barker man has pleaded guilty to chasing a backpacker, who he believed had sexually assaulted his girlfriend, through a Mt Barker property. Connor James Robinson, 24, appeared in Albany Magistrates Court on August 31 on one charge of aggravated burglary and commit and one charge of criminal damage or destruction of property. Police prosecutor Sgt Warrick Walker said Robinson entered the victim’s house via an open door about 11.30pm on July 14. Spotting the victim, Robinson and his co-accused chased him through the house. During the chase, Robinson’s co-accused caused damage to the tune of $1800 by kicking an internal door and damaging the area around the lock which was pulled from the door. The victim escaped through the backdoor of the property without sustaining any injuries. Robinson attended the Mt Barker Police Station on July 26 and made a full admission to police. Robinson’s defence lawyer Wendy Stewart told the court her client acted in haste without thinking of the consequences. Robinson said he chased the victim down because he believed the victim had sexually assaulted his girlfriend. The victim was unknown to Robinson and his co-accused prior to the incident. Robinson’s application for a spent conviction was opposed by the prosecution with Sgt Walker saying Robinson “should have exercised restraint notwithstanding he had a drink that night”. Magistrate Dianne Scaddan, referring to the alleged sexual assault, said it was the job of the police to conduct investigations into these types of matters. “You took matters into your own hands, and you are not entitled to do that,” she said. Robinson was fined $2000 for the charge of aggravated burglary and $750 for the criminal damage charge. His application for a spent conviction was denied by the court.
