ISH-owned bank Santander has sent 35,000 of its customers pages of other people’s bank statements in a printing glitch, it said.
Customers were sent the first page of their own current account statement but further pages of other people’s, including their account numbers, names and transactions carried out.
Santander insisted there was not enough information in the pages to enable anyone to defraud the people involved, but has written to customers affected and informed the regulator, the Financial Services Authority.
“We are sorry for any inconvenience this has caused and have taken immediate steps to correct this,” said a spokesman for Santander, which has five million customers in the UK.
“This is embarrassing and customers have every right to be upset,” he said.
