Lincolnshire Police are supporting the National Fraud Intelligence Bureau (NFIB) in warning people of a new approach being used by scammers.
Fraudsters have been phoning victims telling them that they have been placed in the wrong council tax bracket for a number of years and that they are entitled to a rebate.
They normally say that this rebate should be worth £7,000. Since mid-July, Action Fraud has received 16 reports.
Once the victim is convinced, the fraudster tells them that in order to receive the rebate they will need to pay an administration fee in advance; the payment they ask for varies between £60-350. The victim provides the details and makes the payment, but then is no longer able to make contact with the person they spoke to on the phone.
It is not thought that the reports have come from Lincolnshire residents but it is a scam that officers believe could be attempted in any area.
If you have been the victim of such a scam, call 101 or Action Fraud.
