A manhunt is under way in Adelaide's north for two men who robbed a post office, terrorising customers and staff.
The men were wielding knives when they burst through the door of the Australia Post Office on Kesters Road at Para Hills at 11.30am.
They jumped the counter and stole cash as well as a customer's wallet before fleeing on foot.
Police said it was fortunate no one was injured.
The men were dressed in grey overalls.
It follows a robbery on Saturday afternoon at the nearby Ingle Farm Shopping Centre in which staff at a jewellery store were robbed at knife point.
The offender left with stolen jewellery.
