Detectives from Frankston Sexual Offences and Child Abuse Unit are investigating a sexual assault that occurred in Frankston last month.
Investigators have been told a 17-year-old girl was sitting on a bench seat on Young Street opposite the Frankston Railway station about 11.40 am on Monday, 29 June.
A man approached the girl before sitting next to her and sexually assaulting her.
The man walked away on foot towards Beach Street but not before the quick-thinking victim managed to take a photograph of the man.
Detectives have released an image and CCTV footage of the man in the hope someone will be able to identify him.
He is perceived to be Caucasian in appearance, with short spikey dark hair and aged between 25 and 40-years-old.
At the time, he was wearing jeans and a blue t-shirt with ‘New York’ motif on the front.
His fingernails were painted, and he was wearing distinctive mustard-coloured shoes.
The investigation remains ongoing and police are appealing for anyone who recognises the man to contact Crime Stoppers on 1800 333 000 or submit a confidential crime report at www.crimestoppersvic.com.au
