Melbourne Crime Investigation Unit detectives are investigating a stabbing in Melbourne's CBD last month.
Police were told a man on a bicycle and a man in a grey Toyota Hilux were having a verbal argument near the corner of Collins Street and Spring Street just before 2.30pm on Thursday 23 February.
It's alleged when the driver put down his car window, the cyclist pulled out a knife and stabbed the victim in his hand.
The cyclist has ridden off east along Collins Street.
The driver of the Hilux, a 24-year-old Mooroolbark man, was taken to hospital with non-life-threatening injuries.
Investigators have released images of a man they believe may be able to assist with their enquires.
Investigations are ongoing into the exact circumstances around the incident.
