Police are urging residents to be vigilant following a spate of courier fraud offences.
The latest scam being used by fraudsters involves victims receiving calls advising them that their credit card details have been used illegally and a suspect is in custody.
They are asked to pass on their cards details and PIN numbers in order for police to be able to interview the suspect.
A courier is then sent to their homes to collect their cards, which are then used by the fraudsters.
Detective Inspector Rob King, Head of the Derbyshire Constabulary’s Economic Crime Unit, said: “Fraudsters are finding new ways to target their victims and this is a particularly sophisticated fraud.
“Not only does the fraudster deceive the victim but they also arrange for someone to attend their home address to collect a credit or debit card. They now have the PIN, the card and an appetite for shopping on their bank account.
“The police would not cold call about a suspected offence.”
