Police are looking for a man who exposed himself to a young girl on a tram earlier this month.
The man was on the route 48 tram on the afternoon of January 22 when he flashed the nine-year-old.
Police say the man wore a black baseball cap and sunglasses.
Investigators believe the man got on the tram at the same time as the child, at the Swanston Street stop.
Police say the child told a relative and when the relative confronted the man he fled the tram.
Anyone with information can contact Crime Stoppers on 1800 333 000.
