Eastern suburbs sex predator probe makes potential breakthrough as man quizzed on attacks A MAN has been interviewed about a string of eastern suburbs sexual assaults in a potential breakthrough in a serial sex predator case. Victoria Police confirmed a 33-year-old Nunawading man was interviewed on March 28 in relation to at least eight attacks. He was released pending further inquiries. Since August last year police have received reports of sexual assaults in suburbs including Lower Templestowe, Doncaster, Box Hill, Balwyn North, Canterbury and Camberwell. Police have been searching for a man of Asian appearance in relation to the attacks. "As the investigation is ongoing it will be inappropriate to comment further," Sergeant Anita Brens said. Police have been hunting a serial sex predator since he first struck in August 2012, and by December set up an information caravan in the Canterbury area in the hunt for clues. In December, Detective Inspector Paul Binyon said police were becoming increasingly alarmed about the string of assaults that had left women in Melbourne's leafy eastern suburbs on high alert. He said police believed there was strong evidence to suggest the sexually motivated attacks could become more violent and serious. I think we've been lucky to an extent. He hasn't been successful in actually raping any of these women," Insp Binyon said. His intent has left us in no doubt that is ultimately his aim. There may be potential for escalation in his offending. It was believed a Canterbury attack on a 27-year-old woman in late November was the man's eighth assault since August 3. The Camberwell woman was walking east along Riversdale Rd after crossing Willow Grove just after 9pm last Sunday when the man approached her. Investigators have been told the victim was grabbed from behind and indecently assaulted. The woman dropped to the ground in an attempt to stop the assault and the offender then ran off. He was last seen heading west along Riversdale Rd and right into Willow Grove, before continuing north. Police last year said they had no doubt the same man was responsible for all the attacks. He said the regular pattern of offending involved Caucasian women being attacked after alighting from public transport. The attacks almost always happened around dusk in quiet residential streets. The offender is described as of Asian descent, aged in his 20s, slim, and about 178cm tall. He was last seen wearing a hooded sweater and loose clothing.
