Police investigating the armed robbery of a convenience store at Gowrie Junction on Sunday night are appealing for public assistance.

Around 7.45pm three men entered the store, one armed with a shotgun, another with a handgun, and demanded money and cigarettes before leaving in a white vehicle.

One man is described as wearing a blue hooded jumper, black shorts and carrying a black back pack.

The second man is described as being Caucasian in appearance, wearing grey hooded jumper, black track pants and carrying a black back pack.

The third man is described as also wearing a grey hooded jumper and black track pants.

All three had their faces obscured by black masks.

Investigators would like to speak to anyone who may have been driving near the Gowrie Community Hall about 7.45pm and seen a white vehicle parked near the telephone box on Old Home Bush Road.

Police believe the vehicle left this location shortly afterwards.
