Police have said they have made an arrest in connection with a major fraud from a credit union in County Antrim.
The BBC understands that a sum approaching six figures is suspected of having been stolen from the Portglenone branch of Bannvale Credit Union.
It is understood that the manager of the branch uncovered the alleged theft in February.
Customers are being reassured that the money is insured and that savings have not been in danger at any stage.
A spokesperson for the Irish League of Credit Unions said that it would not comment on the investigation for fear of prejudicing a future legal case.
A PSNI spokesperson said: "Detectives are investigating an allegation of fraud at business premises in the Portglenone area.
"One person has been arrested and enquiries are continuing."
Correction 16 August 2010: An earlier version of this story incorrectly stated that the investigation involved Bannview Credit Union. Bannview Credit Union, which is based in Ballymoney and affiliated to the Ulster Federation of Credit Unions is not connected to the investigation in any way.
