Melbourne Sexual Offences and Child Abuse Investigation Team officers are hoping to identify a man following a sexual assault of a child in Melbourne earlier this month.
The incident occurred at a restaurant on Swanston Street about 6.30pm on 1 July.
Police have been told a 15-year-old girl was entering the venue when an unknown man approached and grabbed her lower body area.
The teenage girl managed to run up the stairs and alerted friends who were already inside.
It is believed the same man harassed the other teenage girls when they entered the venue and followed them inside before being asked to leave by staff.
Investigators have released images of a man who they believe may be able to assist with their enquiries.
The man is perceived to be Caucasian in appearance, aged 40-50 years-old, with a solid build and long brown hair.
He was wearing a grey jumper and dark pants at the time.
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
