Businesses in Newark are being warned to watch out for a batch of bogus bank notes circulating in the area.
There have been five recorded incidents since the beginning of August of fake £20 notes being used in the town, with forged £10 and £5 notes also seized.
The latest seizure was £65 from the Post Office, in Kirk Gate, after staff flagged it with police after receiving it from a number of businesses in the area.
Police are now asking people in the Newark area, specifically retailers and the owners of bars and clubs, to be vigilant against counterfeit currency.
Pc Hollie Shortley said: “It is a criminal offence to knowingly retain or pass on counterfeit notes.
“If it doesn’t look right, if the paper feels different to other genuine money you have, or if you have doubt about the holographic strip, watermark or metallic thread then report it to the police.”
Anyone who suspects they have been supplied with or knows the source of the fake money is asked to contact Nottinghamshire Police on 0300 300 99 99 or call Crimestoppers anonymously on 0800 555 111.
