A man who attempted to rob a Boston pub left empty handed after being told the member of staff present had no access to the till.
A police spokesman said the incident happened at about 3.45pm on Wednesday when the man entered the Magnet Tavern, in South Square, just after it had opened and was empty of customers.
They said the man approached the bar and demanded money from the lone female member of staff.
After being told that the member of staff had no access to the till, police say the offender left the building empty-handed and is believed to have got into a silver vehicle, possibly a Ford Focus.
The spokesman added the man is described as short, of stocky build, with short, dark hair and a foreign accent.
He was holding a small knife at the time of the incident but, although the victim was left very distressed, she was not physically hurt.
