ACT Policing is investigating an aggravated robbery which occurred in Wanniassa early this morning (Thursday, May 23).

About 1.25am three people entered the 7 Eleven Service Station armed with knives and threatened the staff member, demanding cash.

The staff member complied with their demands handing over a small sum of cash. The offender also took some cigarettes and chocolate bars.

Police believe they left the area in a car parked around 200 meters from the service station.

Detective Sergeant Donna Parsons commended staff for complying with the offender’s demands.

“In these situations it is important for victims to remember their personal safety is of paramount importance. Property can be replaced, people can’t,” Detective Sergeant Parsons said.

All three offenders had black cloth covering their faces and are believed to be young, possibly teenagers.

The first offender was wearing a cap, green camouflaged hooded jumper, grey undershirt, and grey tracksuit pants with white stripes down the side, black shoes and white gloves.

The second offender was wearing a black hooded tracksuit top with white stripes down the sleeves and white gloves.

The third offender was wearing a black hooded jumper, black tracksuit pants with two white stripes down the sides, white sneakers and white gloves.
