Bank customer data sold on eBay

An investigation is under way into how a computer containing bank customers' personal data was sold on an internet auction site.

The PC, which was reportedly sold for £35 on eBay, had sensitive information on the hard drive.

The Royal Bank of Scotland (RBS) and its subsidiary, Natwest, have confirmed their customers' details were involved.

RBS says an archiving firm told it the PC had apparently been "inappropriately sold on via a third party".

It said historical information relating to credit card applications for their bank and others had been on the machine.

The information is said to include account details and in some cases customers' signatures, mobile phone numbers and mothers' maiden names.

RBS and Natwest - two of the three businesses involved - said they are taking the issue very seriously and are working to resolve it "as a matter of urgency".

A spokeswoman for data processing company Mail Source, which is part of the archiving firm Graphic Data, said it was investigating how the computer equipment had been removed from a secure location.

"The IT equipment that appeared on eBay was neither planned nor instructed by the company to be disposed."
