On Friday March 17, at about 7.50pm, three offenders entered the One Stop Shop, in North Leas Avenue, brandished knives and made off with a quantity of cash.
Three men have been arrested in connection with the incident, and released on bail as enquiries continue.
Now police officers have released CCTV of the incident showing three men in balaclavas.

A blue sack barrow with two wheels was also taken to the location by the offenders. Police would like to know if anyone is missing such an item, or has had one stolen which has not been reported.
As part of this investigation, officers are requesting any dash-cam footage from motorists who were in the vicinity of North Leas Avenue around the time of the incident.
