Newcastle police have arrested a 21-year-old man over an armed robbery at a Mayfield service station.

It’s alleged the man went into the Maitland Road business just after 6am, and produced a knife while demanding cash from the employee.

He ran off with a sum of cash, but detectives used CCTV footage to track the man down and he was arrested soon after at a nearby house.

It’s understood the man is also wanted over a number of other similar incidents.
