On the 09-07-13 just after 4.00 pm a thirty-three-year-old female got off a bus on the corner of Mt Dandenong Road and Norton Road when she was approached by an unknown male in a red sedan. The assailant then threatened the female victim that he had a gun and a knife and she was forced to enter his motor vehicle. The assailant then punched the female victim to her face and repeatedly sexually assaulted her. The assailant then drove to Jumping Creek Road Reserve in the Warrandyte State Park where he again sexually assaulted her and then told her to get out and he drove off with her mobile phone. The victim managed to flag down a passing motorist and she was soon transported to hospital and treated for a broken nose. Police from the Sexual Crimes Squad are appealing for anyone with any information to contact them..
