Organised phone thieves are targeting pensioners in Arnold by pretending to be HMRC or the tax man and demanding hundreds of pounds from their victims.
The scam has been highlighted after a rise in reports of calls to elderly and vulnerable residents in the Arnold area which has prompted police to issue an alert.
The callers are telling victims they owe money from 20 or more years ago and that unless they pay an amount of money to the caller, they will be taken to court and will have to pay a substantial amount more.
A spokesman for Nottinghamshire Police said: “Can we please remind residents that the HMRC and other Government Departments would not contact you by telephone and ask for money that is owed to them or, threaten you with court action.
“If you get a call like this, please don’t pay anything upfront. Take steps to verify the caller, ask if you can phone them back on a known number, for example or request proof in writing. If you’re unsure, you can always contact HMRC and ask their advice or call us on 101.
They added: “Please ensure that your elderly and vulnerable loved ones are made aware so we can help to put a stop to this fraud and prevent more victims being taken advantage of.”
