Statement on Mail on Sunday article
09 Feb 2014, 10:30 GMT
We are grateful to the Mail on Sunday for bringing this to our attention and we contacted the Information Commission and other regulators on Friday as soon as we were made aware.
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. Based on what we have seen, this appears to be data from 2008 or earlier.
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.
