Police officers in Tayside are hunting at least one man believed to have been widely circulating counterfeit currency.
Shops in Kirriemuir, Forfar, Arbroath, Dundee, Stanley and Auchterarder have all been left out of pocket in recent days.
Each was caught out by an individual offering fake £50 notes as genuine money, with officers in a number of areas investigating.
Police Scotland has urged retailers and shoppers alike to be aware of the incidents and take extra care.
A description has been offered of one man in particular whom they are keen to speak to in connection with the offences.
He is in his mid-twenties, with dark brown hair and a beard, and spoke with an Irish accent.
The man was seen in the Kirriemuir area on the afternoon of Tuesday July 18.
All retailers are advised to check all notes received, in particular Bank of Ulster £50 notes bearing serial number D1233901, and report any that do not appear to be genuine.
Anyone who may know the man or who has information that could assist with enquiries is asked to call Police Scotland on 101 or the charity Crimestoppers anonymously on 0800 555 111.
