Police are re-issuing a fresh warning over a scam in which a fraudster pretends to be a police officer.
Officers believe the fraudsters target elderly people and call on land lines late at night or early in the morning.
The warning comes after six people reported receiving such phone calls in Cambridgeshire last night (Thursday).
In the scam, the caller claims a criminal has been arrested with a substantial sum of money on them and a list of names and addresses, including the victim’s.
The phoney officer then advises the victim to call their bank using a number on the back of their bank card, or the police on 101. The victim hangs up but the caller does not and the call is not terminated.
As a result and without realising it, the victim starts talking to the fraudster again, thinking they have called their bank or the police.
Following a conversation, the offender claims he will need to examine the victim’s bank card and will also need their PIN number as it might be compromised.
The caller says he will send a courier to collect the card before a smartly dressed man arrives at the victim’s home. The card is then taken and the PIN number used to withdraw cash.
Inspector Steve Poppitt said: “Banks will never ask for your PIN number over the phone and you should never give it out.”
