Police are seeking public assistance to locate a 22-year-old French man who allegedly sexually assaulted a woman in a Melbourne laneway in the early hours of New Year’s Day.

Officers have been told the victim was with friends at a nightclub when a man helped her from the dance floor after she fell. 

Detectives believe the same man sexually assaulted the woman at about 4:30am in Coors Lane, which runs between Little Bourke and Lonsdale streets, before leading her to Little Bourke Street and leaving the area.
