Detectives from the Latrobe Family Violence Investigation Unit are making a fresh appeal for public assistance following an incident in Foster seven years ago.
Investigators believe an unknown man gained entry to an unoccupied residential address on Station Road about 10am on 23 March 2013.
The man, who was naked from the waist down, stood at the front window inside the house.
He then performed an obscene act in view of four children who were sitting in a parked car outside.
Seven years ago, police released a digital composite image of a man after speaking to several witnesses.
After receiving new information this year, investigators are re-releasing the image in the hope someone may be able recognise him.
The man is perceived to be Caucasian in appearance, was aged approximately 30-40 years old, and had grey and black slicked down hair.
Anyone with information about the incident or with information about the identity of the man is urged to contact Crime Stoppers on 1800 333 000 or visit
