Assistance is being sought from the public to identify two people who robbed a service station in the Lake Macquarie area overnight.

It was about 6.30pm (Saturday 13 August 2016), when two people – who had their faces covered – approached the business on the Pacific Highway at Highfields.

The store attendant locked the doors but the two people – and one of whom was armed with an iron bar – forced their way inside; the attendant then ran into the store room.

The couple took cash and ran from the store and police were alerted.

Police from Lake Macquarie Local Area Command established a crime scene and specialist forensic officers were called in.

Police now have descriptions of two people they believe can assist with this investigation.

The first person is male, described as being of Caucasian appearance, about 175cm tall and a medium build. At the time the man was wearing black three-quarter shorts and black shoes.

The second person is female, described as also being of Caucasian appearance, about 165cm tall and a thin build with blonde hair. At the time she was wearing blue track pants with white stripes and shoes.

Both had their faces covered.
