Police in North East Fife are urging local businesses to remain vigilant after receiving reports of counterfeit currency in the area.
Since the beginning of February, there have been seven reports of fake notes being used at shops throughout the region, with four stores in Auchtermuchty, Cupar and St Andrews having been targeted in the past few days.
A number of similar incidents have occurred in other areas of Fife during the same time frame with the premises targeted varying from local grocery stores to supermarkets and clothes retailers.
On each occasion a child believed to be between 11 and 15-years-old, has entered the store and bought a low-value item using a forged £50 note.
They are then given genuine currency as change, leaving each business out of pocket.
Retailers are now being asked to ensure staff check notes thoroughly and report any suspicions they have about any transactions to police.
Sergeant Pat Turner from St Andrews Police Station said: “It is clear that adults are using children in the commission of this crime in an effort ensure success when offloading the counterfeit currency.
“All business premises should remain alert for this scam and retain any forged money that anyone attempts to use as payment so that it can be passed to police.
“In addition, anyone with information that can help the police identify whoever is responsible for these offences is asked to get in touch with us as soon as possible.”
Anybody with information is asked to contact Police Scotland on 101 or alternatively the charity Crimestoppers on 0800 555 111.
