Police are investigating an assault on a man allegedly dragged from his car in Adelaide's north by two masked attackers who then stole the Commodore before crashing it into another vehicle.
Police said the man was asleep in his green VY Commodore on Jessie Road at Paralowie in Adelaide's north when he was dragged from his car and assaulted by the masked attackers about 4:30am.
The two men then allegedly stole the car and sped off.
The victim, a 33-year-old from Paralowie, was treated at the scene.
About 20 minutes after the incident, police were called to Edinburgh Road near Sturton Road at Edinburgh after reports of a serious crash.
When police arrived, they found the victim's green VY Commodore had collided with a Mitsubishi Lancer.
Police said the Commodore's driver, a 34-year-old Yorke Peninsula man and the driver of the Mitsubishi, a 38-year-old Mawson Lakes man, were still at the scene and had serious but non-life threatening injuries — but the passenger of the Commodore had left.
The two men were taken to the Lyell McEwin Hospital for treatment.
Police searched the area, but have so far been unable to find the man, and said they have serious concerns for his welfare.
There are road closures and restrictions in place on Edinburgh Road and Sturton Road.
Stolen Subaru found torched
Police are also investigating a separate incident, which involved a stolen car being set alight after a short chase in Elizabeth South.
Patrols spotted a black Subaru Liberty travelling along Quinlivan Road at Pooraka about 12:45am.
Checks on the car revealed it had been stolen from a home in Paradise on Wednesday.
Police activated their emergency lights to try to stop the vehicle, but it took off from them at speed.
They followed the car for a short time west onto Montague Road before ending the pursuit due to safety reasons.
Just after 1:00am, police were called to Ridley Road in Elizabeth South after a resident reported seeing a group of men pull up in a black Subaru and flee, with the car bursting into flames shortly after.
Police searched the area but have not yet found the suspects, and the car was towed from the scene.
Police have asked anyone with information about either incident to contact Crime Stoppers, on 1800 333 000.
