Detectives are appealing for public assistance after a 43-year-old man from Truganina picked up two men in Latrobe Street Melbourne, following a brief interaction, on 3 December about 4.30am.
The men directed the 43-year-old Truganina man to park his red 2019 Audi Q2 along Munster Terrace in North Melbourne before a confrontation occurred in the car.
During the incident, one of the men produced a knife and the victim suffered minor injuries as he was pushed from his car onto the road.
The pair drove off in the Audi and headed towards Arden Street, North Melbourne.
The Audi was recovered in January, but the offenders are yet to be identified.
Anyone with information is urged to contact police.
