Police in Fife are urging businesses across the Kingdom to be vigilant after recent incidents of counterfeit currency being used as payment.
One man has already been charged in connection with an incident in North Street, Lochgelly on Thursday but other suspects are outstanding.
The 50-year-old appeared at Dunfermline Sheriff Court on Friday.
Since the first week of September, there have been several reports of fake notes being used at shops across Fife with stores in the Kingdom Centre, Glenrothes, High Street, Auchtermuchty, Nelson Street, Tayport, High Street, Newport-on-Tay, Market Street, St Andrews, North Street, Lochgelly and Main St, Cairneyhill having been targeted.
The suspects bought a low-value item in each store using forged £50 or £20 notes. 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 to police.
Detective Inspector Colin Robson said: “I am urging all business premises across Fife to be on their guard in respect of this scam and ask for members of the public who are dealing with cash to check high value banknotes before accepting them as payment for goods.
“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.”
Those with information can contact Police Scotland on 101 or alternatively the charity Crimestoppers on 0800 555 111.
