North Wales Police are urging householders to be vigilant when giving personal details over the telephone.
The warning comes after reports have been received at the force’s control room in St Asaph that calls are being made by people purporting to be from the claims court in London.
Calls have been received in Anglesey and Gwynedd by people who are claiming to be calling on behalf of a local authority tax department. They claim that individuals have been placed in the wrong council tax band.
They then ask for a credit card number so that a refund can be given.
The individuals concerned have checked with both Gwynedd and Anglesey County Councils who have told them they are unaware of these issues.
Police are advising people who receive such calls not to disclose their personal or bank account details and if they have any concerns or questions regarding their council tax banding they should contact their local authority.
If anyone is aware of people carrying out this type of fraud they should report it to North Wales Police, on 101, if calling from Wales, or 0845 607 1001 (Welsh line) 0845 607 1002 (English line) or Crimestoppers anonymously on 0800 555 111.
