More warnings of scam calls
Derbyshire Police say they've received more reports
Officers say it's particularly with regard to scammers posing as police officers on the phone trying to con people out of cash.
They go on to say that fraudsters often target geographical areas where they know elderly or vulnerable people live, so to let any family or friends who could be vulnerable know about the activity.
The reports have come from South Wingfield, Matlock, Bakewell and Chesterfield.
Different names and reasons are being given, but the callers are telling people that they are a genuine police officer and that they need to call 999 to verify their identity.
After the victim hangs up to make that 999 call, the scammer keeps the line open and manipulates them during the second call, making them believe that their card has been cloned and used in areas of London.
The caller is then told that arrests are going to be made and they can assist the investigation by transferring large amounts of money to other accounts.
Derbyshire Police say they will never ask anyone to transfer large amounts of money into other accounts, and if you receive a call like this you should not give out any personal information and hang up immediately.
Then, to wait for five minutes or so and make sure you can hear dial tone before ringing them on 101.
