Transit Crime Investigation Unit detectives are appealing for public assistance after a man performed a lewd act in West Footscray in March.
Investigators have been told a 41-year-old woman was sitting on a bench at the West Footscray Train Station forecourt when an unknown man approached her about 4.10pm on Wednesday, 12 March.
It is understood the man inappropriately touched himself beside the woman, before getting up and boarding a Sunbury-bound train.
Investigators have released an image of a man they believe can assist with their enquiries.
The man is perceived to be Caucasian in appearance and in his late 30's, with dark, balding hair.
He was wearing a black long-sleeve top and black pants.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report at www.crimestoppersvic.com.au
