The Charity Commission for Northern Ireland has ordered a bank to provide information about the South Derry Cultural and Heritage Society as part of its investigation of concerns raised about the charity.
The CCNI issued the order to the Bank of Ireland on Thursday last week, the regulator’s website shows.
A spokeswoman for the commission said: "The Charity Commission for Northern Ireland is investigating a concern in relation to the South Derry Cultural and Heritage Society. As part of this work, the commission made an order on 16 April 2015 requesting the Bank of Ireland to release documentation in relation to the organisation.
"The commission is not in a position to comment further on this issue. This is because the commission is an effective and fair regulator of Northern Ireland charities and, as such, would not wish to discourage any parties from coming forward with confidential concerns or information about a charity, or prejudice any current or potential investigation."
The society, which is staffed entirely by volunteers, runs community activities including yoga, martial arts and youth projects. It had an income of about £13,000 last year, a spokesman for the society said.
He said he did not want to comment on the investigation, but said the charity was cooperating with the regulator and had provided the information requested before the commission made the order.
"All information it requested has been provided – we were just a day or so late," the spokesman said.
