Tesco Bank cyber-thieves stole £2.5m from 9,000 people

Bank announces total sum as it reassures customers that they have been refunded and that normal services have been restored

Tesco Bank has revealed that the "unprecedented" attack on its online accounts at the weekend resulted in the loss of 2.5m. The banking arm of the supermarket chain also revised down the number of accounts from which money was removed from 20,000 to 9,000 and announced that banking services had been restored for all its customers.

Tesco bank issued its update hours after Andrew Bailey, the chief executive of the Financial Conduct Authority, told MPs that the incident was unprecedented in the UK and regarded as serious. Bailey told the Treasury select committee that "there are elements of this that look unprecedented and it is serious, clearly".
