Detectives from Wyndham Crime Investigation Unit are appealing for information after a teenage girl was inappropriately touched by a man at a shopping centre in Werribee last month.
Police said that a 16-year-old was walking with her mother through the centre about 1pm on July 14.
The pair were on an escalator when a man ran up behind them, allegedly grabbed the girl on the backside and ran off.
The man is perceived to be of Asian appearance, tall with a slim build and possibly aged in his late teens.
At the time of the incident he was wearing a dark blue tracksuit with a light blue stripe up the side.
Detectives have released images of a man they wish to speak to in relation to the incident.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
