Police are investigating an indecent exposure at a Cheltenham shopping centre last month.
Investigators have been told an unknown man entered a Nepean Highway retail store about 11.05am on Friday 8 May.
The man walked down an aisle and began masturbating before being asked to leave the store.
He then exited the shopping centre on foot and walked towards Garfield Street.
Investigators have released images of a man they believe may be able to assist with their enquiries.
The man is approximately 170cm tall, with a medium build and grey hair.
He was wearing a red polo with horizontal white stripes, a black jacket, beige pants and had reading glasses around his neck.
Anyone who recognises the man or with information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report at www.crimestoppersvic.com.au
