A shop assistant has been left badly shaken after an armed robbery at a Londonderry newsagents.
Police have confirmed that one of the gang was armed with a suspected firearm while another was wielding a knife.
A third man was brandishing a hammer.
The gang entered the shop in the Great James Street area of the city centre at 8.45pm on Tuesday.
They made off a short time later with a sum of money and a mobile phone.
A PSNI spokeswoman said: “No one was injured during this incident. However, the member of staff was left badly shaken.
“All males were approximately 5ft 11ins in height with their faces partially covered.”
SDLP councillor Ann Donnelly said such actions were a disgraceful attack on a local business and community resource.
She said: “This must have been a terrifying ordeal for the person who was working in the shop at the time and my sympathy goes out to them.
“Hopefully whoever was behind this attack will be caught and brought to justice. I would call on those involved in this type of activity to desist immediately from upsetting people in the community.”
Police have urged anyone with information about the incident to contact Strand Road CID on 0845 600 8000 or the independent charity Crimestoppers anonymously on 0800 555111.
