An OAP was fleeced of £8,000 after a conman tricked her into handing over her bank card and details.
The raid on the elderly woman in Hebburn has prompted a police warning.
Officers are urging people not to hand over bank details to strangers and - if in doubt over a caller to their home - not to be afraid to shut the door and contact police.
The warning came from Neighbourhood Sergeant Matt Hough during a recent meeting of the Hebburn Community Area Forum.
He told the meeting the pensioner was contacted by phone by someone claiming to be from her bank and saying it needed to collect her bank card.
He said: “A short time later a man came to her house and she handed over her bank card and pin number.
“A transaction of £8,000 was later taken from her account.”
He said those believed to be involved in the incident - which happened at the end of July - had been identified, but urged people to remain vigilant.
He added: “If you are in any doubt about whether a person is who they say they are, if they are on the phone - hang up. If they are at the door, shut it and call the police. If they are not successful with you, they could move onto someone else.”
He also appealed to neighbours and families to look out for them.
Last month, a pensioner in Whitburn was left £500 out of pocket after being tricked into handing over cash by a bogus caller who carried out work on her property which had only been done the year before.
It is understood the 87-year-old had been visited at her home by a cold caller who persuaded her work needed doing to her home and quoted her £35.
Once the work started, more jobs were added and the bill eventuially reached £500
