A group of masked men made off with a sum of money after an armed robbery at a fast food takeaway in Portadown in the early hours of Saturday morning.
Police received a report shortly after midnight that two masked men entered the rear of the premises on Lurgan Road.
Both were reported to be carrying weapons including a suspected firearm and a crowbar. A third man remained at the rear door of the property.
The two men searched the counter area and made off with the third man after taking a sum of money.
Police are not sure if a getaway vehicle was used or the suspects made off on foot.
Detective Sergeant James Johnston said that staff members present during the incident were not physically injured, but had been left understandably shaken.
