A male is wanted over the alleged sexual assault of a teenage girl on a bus at Hampton Park.
The male allegedly boarded the bus outside a Hampton Park shopping centre on Hallam Road just before 4pm on Saturday, 17 February.
Transit Safety Division detectives say he allegedly sat next to a 15-year-old girl, put his arm around her and sexually assaulted her.
The girl broke away from the male to sit closer to the driver, police say.
The male disembarked from the bus at a shopping centre on Overland Drive in Narre Warren about 4.20pm.
He is described as of Middle Eastern appearance, in his late teens or early 20s, 175 centimetres, medium build with slicked-back black hair and slight facial hair above his lip.
He was wearing a white Ecko-brand T-shirt with navy blue sleeves, beige pants and black shoes.
Police have released an image of a man who may be able to assist with their enquiries.
