Confidence tricksters are targeting borough residents by using a telephone scam to try and steal money from their bank accounts, town hall finance chiefs are warning.

Fraudsters are pretending to be either council tax or housing benefit officials and promising residents tax or benefits rebates to get their bank details and personal information.

Once armed with this important data, the fraudsters can milk their victim's bank accounts.

In one case reported to the council this week the con artists telephoned an elderly resident and informed him that he was due a housing benefit rebate of some £1,300 - which could only be paid if he revealed his bank account details.

Later on the resident realised that he may have fallen victim to a scam and contacted staff at his bank. They told him that his account had been emptied of just under £100. Fortunately the bank has reimbursed the resident and are understood to have launched an investigation to find out where the stolen money was transferred.

The council's director of finance Chris Buss said: "These calls are a complete and utter con.

"People should not be taken in by them - and they should never give any sensitive personal information like bank account details or their date of birth to people who ring up out of the blue.

"No genuine town hall employee would ever make such a call and it would simply not be necessary for us to have your bank account details for this purpose.

"My advice to anyone who gets these calls is refuse to tell them anything at all and simply hang up."

Anyone receiving this kind of telephone call is strongly advised to report the matter to the council's trading standards team on (020) 8871 7720 or by emailing tradingstandards@wandsworth.gov.uk.
