Arrest made after 106m Capital One user details breached

Paige Thompson - the alleged hacker who stole the personal details of about 106 million Capital One users across the US and Canada - was arrested overnight, after reportedly boasting about the breach online.

Capital One said the data included the names, addresses and phone numbers of people who applied for its products.

The data breach was believed to be one of the largest in banking history but the hacker did not gain access to credit card account numbers, the company said.

The firm added that the breach affected approximately 100 million individuals in the US and six million people in Canada.

It added that about 140,000 social security numbers and 80,000 linked bank account numbers were compromised in the US.

The retail banking giant said it would notify those affected, and would provide them with free credit monitoring and identity protection.

"While I am grateful that the perpetrator has been caught, I am deeply sorry for what has happened," said chairman Richard Fairbank.

"I sincerely apologise for the understandable worry this incident must be causing those affected and I am committed to making it right."
