Barclays has launched an investigation after thousands of files of customers who sought advice from the bank were reportedly stolen and sold on to rogue City traders.
The Mail on Sunday reports customers from its financial planning arm had details of their earnings, savings, mortgages, health issues and insurance policies passed on to brokers.
The information came from a whistleblower who passed the newspaper 2,000 customers’ details but claimed it was from a batch of up to 27,000.
He said the files are for sale at £50 per customer between December 2012 and September last year and estimates up to 1,000 people could have been scammed.
All customers passed over data during a factfind with an adviser.
A Barclays spokeswoman says: “Our initial investigations suggest this is isolated to customers linked to our Barclays Financial Planning business which we ceased operating as a service in 2011.
“We will take all necessary steps to contact and advise those customers as soon as possible so that they can also ensure the safety of their personal data.
“Protecting our customers’ data is a top priority and we take this issue extremely seriously. This appears to be criminal action and we will co-operate with the authorities on pursuing the perpetrator.
“We would like to reassure all of our customers that we have taken every practical measure to ensure that personal and financial details remain as safe and secure as possible.”
FortyTwo Wealth partner Alan Dick says: “People do not trust banks and this is another example of that lack of trust. This type of data leak is easier in a large firm because they do not know where everything is held whereas a small IFA firm would know.”
