Police in Sydney’s west are appealing for public help as they continue their inquiries into an armed hold-up at a Cranebrook service station last month.

About 11pm on Friday 27 April 2012, a man entered the service station on Andrews Road, Cranebrook, and threatened the female console operator with a knife.

The offender stole cash and cigarettes before fleeing on foot.

No one was injured in the robbery.

Penrith Detectives have been conducting inquiries into the incident.

They have now released images of a man they believe might be able to assist with their inquiries.

He’s described as being aged in his early 20s, of Caucasian appearance and 180cm tall with a medium build.
