Staff at a petrol station barricaded themselves in an office when an armed thief walked into their workplace.
About 4am on Saturday, a man allegedly armed with two large knives entered a service station on Marsh Street, Armidale.
Two staff members observed the offender approaching the console area and immediately moved to a nearby office where their manager was located and barricaded themselves in.

The man, who was wearing a hooded jumper, bandana and wearing gloves fled the location and was last seen heading north towards the carpark adjacent to the service station.
A crime scene was established, and an investigation is underway.
