Just after 3am, two men armed with a hammer and a weapon believed to be similar to a tomahawk stormed a service station on Queen Elizabeth Dr.

The men demanded money and cigarettes from a male employee working behind the counter.

They then fled with the goods, and were last seen running along Queen Elizabeth Drive.

The employee sounded the alarm and police were alerted, arriving within minutes.

A crime scene was set up and police said no one was injured in the robbery.

Police have spent the morning canvassing the area, which has been combed by forensic crews.

Officers are now appealing for help to find the offenders.

The first man is described as being of medium build, approximately 168cm tall and was last seen wearing a dark hoodie with white cords hanging from the neck and waist, and dark pants.

The second offender is described as being of medium build, approximately 167cm tall and was last seen wearing a dark jacket and dark pants.

Police said both men had their faces covered.

Anyone with information on the identity of the offenders or who saw two men acting suspiciously is urged to contact Armidale police on 6771 0699.
