Police are looking for a man who allegedly followed a woman while masturbating in Shepparton earlier this month.
Police allege the man walked closely behind the 42-year-old victim at the intersection of Gowrie St and Balaclava Rd about 11am on Friday, November 12.
When the woman looked back at the offender, he had allegedly started touching himself, police said.
The man then walked away and was last seen heading south along King St, according to police.
Police have released images of a man they believe may be able to assist with their inquiries.
The man is perceived to be Caucasian in appearance, with a tall thin build, blue eyes, large nose, emaciated cheeks, short sandy wispy hair and short facial hair.
He was wearing a black baggy jacket with a hood, blue/grey tracksuit pants and white runners.
Anyone who recognises the man or who has with CCTV or dash-cam footage is urged to contact Crime Stoppers on 1800 333 000 or at www.crimestoppersvic.com.au
