Bank of Ireland has apologized after fixing a technical problem that allowed customers to withdraw or transfer more money than they had in their account.

The technical problem created queues in front of ATMs throughout the day and into the night yesterday as word spread that the Bank of Ireland ATMs were handing out free money and the intervention of the police was needed.

Irish media reports today that customers with no money in their account were able to withdraw up to €1,000.

Bank of Ireland has warned users of ATMs or online banking applications that this money will be charged.

“We apologize for the disruption caused by this breakdown. (…) We know that we have fallen short of the level of service that our customers expect from us,” the bank’s announcement states.

Brendan Burgess, founder of AskAboutMoney.com, told RTE television that the bank needed to improve its “clumsy” IT system.

However, he added: “If you know you have no money, but you take €1,000 from the bank account, you are committing fraud. And this is not a problem to do with Bank of Ireland’s systems.”

The central bank of Ireland has fined Bank of Ireland for flaws in its information systems and announced that he is monitoring the consequences of yesterday’s incident.
