Police are investigating an aggravated robbery at Torrensville yesterday during which a man was hit from behind and his car stolen.

At about midday, the victim, having started his car in a shopping centre car park on Henley Beach Road, got out of his car so as to untangle his seatbelt.

As he did, an unknown offender hit him from behind before getting into the victim’s car and driving off.

Having been knocked to the ground, the victim didn’t see his attacker but did see his utility travelling west on Henley Beach Road.

The stolen car is used as a courier vehicle and has the numbers 261 on both guards and badged Aceit Couriers.  It has three roof racks and a red sack trolley in the rear.
