Police were alerted by an alarm at McColl’s newsagents in Arden Road at just after 6am after a masked man entered the shop.
The offender grabbed a female shop assistant by the wrist and demanded money. The woman, in her 50s, suffered bruising and was very shaken but did not suffer any serious injuries.
The man made off with a ‘significant amount’ of cash, and ran out of the shop, turning right toward Costcutter.
Police are currently examining CCTV footage and are keen to hear from anyone around the Arden Road or New Street area of Frankley who may have seen the man before the incident or running away from the scene.
The offender is described as a black male, wearing a ski type mask and a dark parker style coat or jacket with fur trim on the hood.
Anyone with any information is asked to call DS Glen Marriott at Force CID on 101. Alternatively, call Crimestoppers anonymously on 0800 555 111
