Police have issued a fresh warning after a woman in Belper was tricked into revealing her debit card pin number.
The 91-year-old woman, who lives on Over Lane, was visited by a man who claimed to be from a window company. He called at her house between 1pm and 3pm on Wednesday May 11 and suggested she had a window replaced.
He measured up the window and asked for payment in advance. The woman offered to pay by cheque but he refused and asked her to put her PIN in a machine he was carrying.
He then stole her card while she was out of the room and used it to withdraw money from cash machines.
The man was white, in his 40s, about five feet eight inches tall, with short dark hair and a stocky build. He was wearing a long-sleeved red Tee-shirt with a lighter coloured logo on the left.
Officers have warned residents not to be conned by callers at their homes. They should never allow strangers in and should careful about agreeing for work to be done by cold callers.
Anyone who has any information that would help the police inquiry should ring DC Darren Potts on 0345 123 33 33 or call Crimestoppers anonymously on 0800 555 111.
