A masked man with a shotgun has robbed a jewellery store in Adelaide's north-west, smashing display cases with a hammer before fleeing with valuables.
The thief was wearing a balaclava and thongs and armed with a shotgun when he entered the store in Arndale Shopping Centre at Kilkenny about 12.45pm on Sunday.
He broke a number of glass cabinets with a hammer and stuffed jewellery into a large sack during the brazen smash-and-grab.
No one was injured in the incident but some staff members are being treated for shock.
A manhunt is underway for the suspect who was wearing grey clothing, socks and thongs, and police are calling for witnesses.
Police believe the man got away in a grey Ford Territory with registration S044BBR.
Anyone who sees the vehicle is asked to contact police but urged not to approach as the suspect may be armed and dangerous.
