Police are investigating a ram raid at a jewellery shop in Port Lincoln earlier this morning.
Alarms were activated at 5.34am, when a grey 4WD reversed into the front of the store on Tasman Terrace.
A large quantity of jewellery was stolen and the car was last seen on New West Road and later dumped in Carramatta Court with rear end damage.
It is possible the offenders then got into another car.
