A man on the run following an alleged armed robbery has been caught after his car collided with a petrol tanker.

The 20-year-old man, who can’t be named, evaded police for more than a week.

He was arrested after the allegedly stolen Subaru Forester he was driving collided with a B-double near Camperdown, west of Melbourne, on Friday.

The man was found still inside the Subaru, which had rolled into a paddock after crashing into the truck on the Princes Highway about 3pm.

The tanker was run off the road and bogged in the accident.

The 20-year-old man was one of two men on the run after the daylight robbery of a motor home in Warrnambool on August 25.

Police allege three men, two armed with guns, pushed open the 23-year-old victim’s door at 7.30am and demanded cash.

They stole the victim’s wallet and a cash tin, and fled in a red Holden station wagon.

Two other Warrnambool people – a 29-year-old woman and a 26-year-old man – have been charged over the armed robbery and remanded in custody.

Another co-accused, Keiarhn Carter, remains on the run.

Police identified the crash victim as a person of interest at the accident scene.

He was airlifted to the Royal Melbourne Hospital, where he remains on Sunday under police guard with injuries to his arms and legs.

Police found a loaded, sawn-off shotgun inside the Subaru, as well as stolen property and implements believed to have been used in break-ins and armed robberies.

Officers allege the vehicle was stolen during an aggravated burglary in Sandhurst about two weeks ago.

A 15-year-old Camperdown boy was also in the car. He suffered minor injuries and was taken to Camperdown Hospital before being released into police custody.

The boy was interviewed in relation to the collision and other criminal matters and has been remanded in custody.

Anyone who has information about fugitive Keiarhn Carter can contact Crime Stoppers on 1800 333 000.
