Police are investigating following the armed robbery of a supermarket in Rothwell this morning.

A man walked into the business on Bremner Road around 5.10am, selected a flavoured milk from the drink fridge and approached the front counter.

He then put a bag on the front counter and demanded money and cigarettes from the female cashier before revealing what appeared to be a firearm from the pocket of his jumper.

The cashier complied and handed over a sum of cash and the man fled the scene.

Police have released CCTV images (below) of the man who is described as Caucasian in appearance, around 170cm tall with a medium build, short dark hair with lines shaved into the side.

He was wearing a black hooded jumper with black tracksuit pants and was carrying a black bag.

Police are urging anyone who may recognise the man or have further information about the incident to contact Policelink or Crime Stoppers.
