Hampshire Man Conned Out Of Thousands Of Pounds
The 83-year-old from Lee-On-Solent was called by a man saying he was from the Southampton Police Fraud Department last month.
He was talked into handing over his bank and credit cards, more than two and a half thousands pounds were withdrawn from his accounts.
On Saturday, August 30 the 83-year-old victim received a call from a man purporting to be from the 'Southampton Police Fraud Department.'
The man explained that there appeared to be a problem with the victim's bank accounts and that he would be sending a courier to the address to collect all of his bank cards relating to the accounts, along with any associated PINs.
At around 3pm a man attended the address of the victim in Avon Close, Lee On Solent, and collected the cards which had been placed in an envelope by the victim.
The victim then became suspicious and intended calling his banks, however before he could do so, he had a further telephone call from another man claiming to be from Natwest Bank.
This man advised the victim that they have received the cards and would return them the next day, putting the victim at ease.
The offenders then made four withdrawals from ATMs totalling £1050 and seven credit card transactions totalling £1,642.84.
The man who attended the address is described as black, well dressed and of a heavy build. Detective Constable Christopher Davies, said:
"This was a despicable crime where a vulnerable member of our community has been deliberately taregtted.
"I am appealing for members of the community to spread the word about this sort of scam, especially to any elderly or vulnerable family members, friends or neighbours. If anyone believes they may have fallen victim to this sort of crime and have not yet reported it to the police, I would urge them to get in touch with us straight away."
Anyone with any information is asked to contact DC Davies at Fareham police station by calling 101 or call Crimestoppers on 0800 555 111, where information can be left anonymously.
