Police are appealing for information following an armed robbery in Lalor on 28 June, Victoria Police say.
Investigators have been told a 35-year-old Lalor man got out of his car at a shopping strip on May Road about 12.30am when he was approached by four men.
It is believed one of the men was armed with a screwdriver, while another had a knife, which was pressed to the man’s throat.
The group demanded the man’s car keys before punching and kicking him to the ground.
He was then struck to the back of the head with the screwdriver.
The group fled with the man’s car keys and mobile phone and took off in his vehicle.
The man was taken to hospital for assessment.
Two of the men are perceived to be of Islander appearance and aged in their 20s.
One was wearing a grey jacket and light grey pants, while the other was wearing a light-coloured hooded jumper.
Police are also searching for the stolen vehicle, a white Citroen C5 SUV with registration SXZ883.
Anyone with information or who may have noticed anyone loitering around the area at the time is urged to contact Crime Stoppers.
