Police are appealing for witnesses after a knifeman threatened staff at a Morrisons store.

The man entered the supermarket on Stirling Way on November 13 at 11.15pm and demanded cash.

But he only escaped with a document of used shopping vouchers which he took from a trolley.

He was seen heading towards the Farriers Estate.

No one was hurt in the incident.

The suspect is black, around six feet tall and of large build. He was wearing a dark coloured hooded jacket, dark bottoms, a scarf, and trainers.

Police believe the man may have been in the store earlier that evening.

Anyone with information is asked to contact DC Chris Payne on 101, quoting crime reference number J1/17/4852
