Police are appealing for information after an armed robbery in Dural.

About 9pm yesterday (Tuesday 20 August 2013), two men entered a take-away food business on Old Northern Road.

While one man kept watch, the other threatened the 25-year-old male staff member with a knife and demanded cash.

The men left the business with an amount of money and were last seen running south.

No-one was injured in the incident.

Police from The Hills Local Area Command established a crime scene, which was examined by specialist officers from the Forensic Armed Robbery Unit.

Detectives are continuing investigations into the robbery, and would like to speak with two men who may be able to assist with their inquiries.

One man is described as being aged in his late teens, and with a thin to medium build. At the time of the incident, he was wearing loose, dark-coloured clothing, a chequered flannelette jacket, and a cloth over his face.

There was no description of the second man, other than his face was also covered.
