A teenage shop assistant was terrified by two masked men who burst into a shop in Melbourne's north brandishing guns and demanding money.
The men, wearing pantyhose over their heads, forced the 17-year-old girl to the floor in front of eight customers at the Supre factory outlet in Riggall Street, Broadmeadows, about 6pm on December 29, a police spokeswoman said.
While the shop worker was on the floor, the robbers opened the tills and emptied them of cash. They then left.
The pair were caught on closed circuit television footage getting into a grey or silver car in the car park.
Police believe a third man drove the getaway car, believed to be a Mitsubishi Outlander with a front nudge bar and slimline roof-racks. It was driven west on Riggall Street and last seen in Somerton Road.
The robbers, who were wearing dark and loose-fitting clothing, are described as being aged in their 20s and between 170 and 180 centimetres tall.
Anyone with information is asked to phone Crime Stoppers on 1800 333 000.
