A knife-wielding masked man escaped with cash after robbing a shop in Derry city centre earlier this week.
It’s the fourth time Siopa, at Great James’ Street, has been robbed in the past 18 months.
The latest raid took place on Tuesday evening shortly after 6.30 p.m. when a man entered the premises brandishing a knife and demanding money.
A 17-year-old shop assistant said she feared for her life as the man pointed the blade at her and ordered her to hand over money.
The schoolgirl said: “He shouted at me and kept saying, ‘Get in behind the f*****g till.
“I was so scared. He was shaking the knife right in front of me. He pointed it towards me at face level. He just kept shouting.”
“It was the scariest thing that has ever happened to me. I was shaking so much that I was dropping the pound coins everywhere. I didn’t know what to do and he didn’t care.”
Shop owner Kevin Doherty added: “I’m just glad nobody was hurt. Times are hard enough in the newsagents’ business these days without this happening.”
Police say the robber - who made off on foot along Lower Road - was wearing a burgundy coloured hooded top and jeans.
