POLICE are again appealing for witnesses to a sexual assault on a work experience student in Glen Waverley more than 20 years ago to come forward.
Detectives from the Box Hill Sexual Offences and Child Abuse Investigation Team were recently alerted to the crime and believe there may be other victims.
The victim, who was 15 years old at the time of the alleged assault, reported the matter to police earlier this year.
The sexual assault, which took place between 1988 and 1989, is alleged to have happened while the male victim was doing work experience with a builder in his 40s. The assaults were said to have occurred across the eastern suburbs, including Glen Waverley.
Police believe other crimes of a similar nature were committed throughout the 1980s and 90s.
Anyone with information about it or similar incidents can call Crime Stoppers, 1800 333 000.
