A woman stood up to her attackers before seeking help, following an alleged sexual assault in Dandenong.
She crossed paths with a group of men of African appearance while walking through Moysey Lane, Dandenong, on Thursday 23 March.
As the victim passed the group, one man doubled back and grabbed her genital area.
The victim confronted the group before turning around, walking to Dandenong Railway Station and reporting the incident to PSOs.
Her alleged attacker was wearing a black cap turned backwards, a black zip-up hoodie and light-coloured jeans with thongs.
Call Detective Acting Sergeant Nathan Sheppard at Dandenong SOCIT on 8769 2200 with any information.
