Police are appealing for information after separate armed robberies of service stations in Wallsend and Mayfield yesterday.

About 12.20am (Wednesday 9 April 2014), a person drove a blue Holden Commodore sedan to a service station on the Industrial Highway, Mayfield, and refilled their fuel tank.

When the person was unsuccessful in paying via the pay wave system, they allegedly sped away from the station.

About 12.30am (Wednesday 9 April 2014), a person entered a service station on Thomas Street, Wallsend, and asked for a packet of cigarettes.

The person allegedly pointed a firearm at the console operator and demanded money.

The attendant complied with their request, and the person fled the station with cash and cigarettes. The offender was last seen walking towards Thomas Street.

In the third incident, about 1am (Wednesday 9 April 2014), a person entered a service station on Maitland Road, Mayfield, and approached the console operator after selecting three ice creams.

The person requested two packets of cigarettes before allegedly producing a handgun and demanding money.

The attendant questioned the offender, who then fled the service station on foot with the ice creams and cigarettes. They were not given any money.

The offender was last seen walking in an easterly direction on Maitland Road.

No description is currently available of the offender.

Police from Newcastle City Local Area Command believe the incidents are linked and ask that anyone with information come forward.
