Police are appealing for witnesses after an armed robbery of a service station in Auburn late last night.

About 10.40pm (Thursday 18 April 2014), the attendant, a 26-year-old man, was on the forecourt of a service station on Cumberland Road, when he was approached by two men walking from Wellington Road.

One of the men grabbed the attendant, threatened him with a knife and forced him back into the shop.

He then demanded money, the attendant complied handing over a sum of cash. The second man also demanded money, before both men ran from the shop.

Police were contacted and officers from Flemington Local Area Command attended, established a crime scene and commenced an investigation.

The scene was examined by forensic specialists.

One of the men was described as large build, about 183cm tall, wearing a white shirt, blue hooded jumper, black tracksuit pants and white shoes.

The second man was described as medium build, about 175cm tall, wearing a blue shirt, dark coloured jumper, grey pants and black shoes.

Investigators would like to speak to anyone who was in the vicinity at the time or saw suspicious behaviour to contact authorities.
