TERRIFIED staff were taken into a shop back room and forced to hand over cash by masked men wielding hammers.
The four workers were closing-up for the night at the Co-op in Huddersfield Road on Monday when two men brandishing claw hammers burst in.
Wearing hoodies and with scarves covering their faces, they threatened the staff and ushered them into a back room.
They then stole cash from a coin safe before leaving.
A Co-operative Group spokesman said: “No-one was hurt in the incident, although the staff were left badly shaken.
“The store re-opened for business as usual the following day, and all the staff will receive counselling and support, as well as additional security measures at the store.
“CCTV footage has been given to the police.”
The suspects were two white men around 5ft tall. One was of a large build, with a chubby face and short, blond hair. He had blue to green eyes.
The only description of the second suspect is that he was slightly taller than the first.
Police are urging anyone who saw anything suspicious or anyone hanging around outside the shop at around 9.45pm to speak to them.
Officers would not say how much was stolen but asked the public to watch out for people having a large amount of coins.
Det Insp Phil Benson said: “It is likely the suspects will try to cash in the coins.”
