Ulster Bank services are back to normal after customers experienced technical problems last night.
The bank says no customers will be left out of pocket as a result of the latest issues with their accounts.
Yesterday evening, account holders reported problems with online purchases and card transactions.
Our customers are reporting that services are coming back on line. We will confirm when all systems have returned to normal service.

The glitch came on Cyber Monday - the busiest online shopping day of the year in the run up to Christmas.
News of the latest Ulster Bank technical glitch came to light on Twitter, with customers complaining their cards had been declined in shops.
Others said they could not complete online transactions.
Ulster Bank, in turn, used its Twitter account to reassure customers it was dealing with the issue.
By midnight, it was saying that services were coming back on line.
It says if any customers are left out of pocket as a result of the problem - it will put this right.
We're aware of some technical issues and are working hard to fix them. Sorry and thanks for your patience

The technical issue has sparked fears among Ulster Bank customers over access to their deposits in the run up to Christmas, it comes after last year's catastrophic technical glitch, which took months to completely resolve and saw Ulster Bank paying compensation to its customers.
