Shop staff and customers are being urged to be vigilant after counterfeit cash was apparently used in New Stevenston.
Police are investigating the incident, which took place at a shop on Clydesdale Street between 12.30 and 1.30pm on Monday, June 30.
Officers are keen to trace two men said to have used the money. One is white, 45-49, 6’, of medium build with short dark hair and was wearing a burgundy top, leather jacket and jeans. The other is 20-29, slim with collar length blond hair and was wearing an ‘oversized’ denim shirt and jeans.
PC Garry Cook, Safer Communities, said: “There is a significant difference in the quality of counterfeit notes compared to genuine notes.
“Print quality, metallic security thread and watermark are three simple ways of checking if a note is counterfeit.
“If anyone suspects they have been handed a fake note, then they should seize it and contact the police.
“It is a criminal offence to hold or pass a note that you know to be counterfeit.”
