Sex attack violent, disgusting: NSW cops A WOMAN who was the victim of a "violent and disgusting" sex assault inside her western Sydney home was targeted at random, police believe. The male intruder climbed into the Oakhurst residence through a window armed with a knife around 8pm (AEST) on Tuesday and sexually assaulted the 31-year-old who was home alone. After the assault, the man took the woman's mobile phone and car keys and fled when the woman's ex-husband arrived at the house to deliver mail, police said. The offender then drove off in his victim's car, running over a neighbour and crashing into a tree. Police Superintendent Wayne Cox on Wednesday said the "highly concerning" attack was unusual for the local area. "It's an extremely violent and disgusting attack," he told reporters at Mt Druitt. It's certainly confronting for the morals of the community. Supt Cox said the victim was "very distraught" following the ordeal. "Police are working with her to get statements and finer details of the offence that has taken place," he added. Supt Cox said the offender was thought to be in his late teens or early 20s, about 160-165cms tall, and possibly of Aboriginal appearance. He said initial inquiries indicated the assault was a "one-off" and that the victim didn't know the man who attacked her. There are no crimes committed in this particular area of that sort of nature, he said. He said police believed the attacker gained entry to the home by removing a fly screen from a window and climbing inside and the attack was a reminder for residents in the area to secure their homes.
