Transit Crime Investigation Unit detectives are investigating after a slingshot was fired at a bus in Coburg on 25 July.
The male offender was seen walking west along Moreland Road, taking shots at several windows and signs.
He then targeted a bus that had stopped to collect passengers on Moreland Road, firing a shot which struck and shattered the window about 1pm.
Luckily the projectile didn’t penetrate the glass and the 22-year-old male victim wasn’t injured by the broken glass.
Detectives have released CCTV and an image of a man they believe can assist with their enquiries.
