Trading standards have been informed that bogus callers are ringing people up pretending to be from Derbyshire County Council.
The caller claims to be from the council wanting to speak to people about an accident they may have had.
During the phone calls residents have been asked for personal information.
DCC cabinet member for health and communities Councillor Dave Allen said: “We’ve had reports from worried residents saying that a council representative has called about an accident they have had.
“We’d like to make it clear that we would never make unsolicited phone calls like this. Our advice is to put down the phone on these scammers and report the call.
“The fraudsters pretend to be from organisations like the county council because people are more likely to trust them.
“Fortunately, the people who have contacted us have realised this is a scam phone call and have hung up in good time.
“We urge all residents to report any phone calls, letters or other scam material which will help us with our investigations and to take action.”
The council are now urging carers, families and friends of older or vulnerable residents to pass on this latest warning, look out for any signs that they may be a victim of scams and to report anything suspicious.
Residents who believe they have been scammed or who know someone who has can get advice and report it to the Citizens Advice Consumer Service on 03454 040506.
