A armed robber threatened terrified staff with a knife at a Co-op store in Luton this week.
The shocking incident took place between 9.55pm and 10.20pm on Wednesday, July 8 at the Co-op in Wigmore Lane.
A man entered the shop and brandished the knife, before demanding money from the till and safe.
He is described as black and stocky. He was wearing a grey hooded top underneath a dark blue one, with a checked scarf, blue Adidas trainers and an Umbro rucksack.
PC Iain Wise, investigating, said: “This was a nasty incident which will no doubt have a long-lasting effect on the shop staff who were working at the time.
“We are keen to get this dangerous man off the streets and are appealing for the public’s help in sharing information.
“We know from our CCTV enquiries that several people passed this store while walking their dogs. If you were in the area at the time we like to hear from you and continue to piece together the events of that night.”
Anyone with information is asked to contact PC Wise on 101, text 07786 200011 or call Crimestoppers anonymously on 0800 555 111.
