Staff at a Sheffield grocery store were left shaken after a masked robber made threats and demanded cash.
South Yorkshire Police have launched an investigation into the incident at the Londis store in Broad Street in the city centre.
A man whose face was obscured by a balaclava entered the shop at around 9.10pm on Thursday and threatened employees before running off with cash from the till.
No-one was injured in the incident but staff were said to have been left ‘incredibly shaken’ by the ordeal.
Officers say the suspect ran off in the direction of Park Square roundabout.
He was wearing dark clothing, black trainers, black gloves, a black balaclava and was carrying a black cloth drawstring bag.
Witnesses have described him as being of medium build and about 5ft 10ins tall.
Detective Constable Thomas Ryan, of South Yorkshire Police, said: “This was a cowardly act which has caused a great deal of upset to staff who were on duty that night.
“I urge the public to come forward and provide any information they can which will help to bring this man to justice.”
Witnesses and anyone with any information which may help police in the search for the masked robber are asked to call South Yorkshire Police on 101.
They can also contact Crimestoppers anonymously on 0800 555 111, quoting incident number 1,244 of October 17.
