Data protection and financial regulators are investigating Barclays after a whistleblower claimed the bank leaked 27,000 customer records.
The security breach was reported by the Mail on Sunday, which has seen the files of 2,000 Barclays customers.
Fraudsters buy such data to carry out investment scams. "This illegal trade is going on all the time in the City. I want to go public to stop it getting bigger,” the whistleblower said.The whistleblower claimed the files were a sample from a stolen database of up to 27,000 files, worth around £1.35m. The whistleblower said an unnamed firm of rogue brokers gave him the files to sell.
