Police are warning shopkeepers in Cornwall to be aware of a fraud known as “ringing the changes.’’
Two men of Asian appearance are being sought after defrauding store owners in a number of towns in the county including Camborne and Wadebridge.
The scam involves asking shop staff to change currency and then confusing them into handing back a larger sum of cash.
Police say the latest offence was at a shop in Wadebridge last night, when the two men bought an item of low value and then asked for a number of £20 notes to be exchanged.
Police are appealing for information and can be contacted on 101, quoting crime reference AC/14/591.
