Prominent loyalist Jamie Bryson has been asked to provide information about Nama’s Northern Ireland loan sale.
Chairman of the Stormont committee investigating the £1.1 billion deal to sell the organisation’s massive property portfolio, Daithi McKay, said it would write to Mr Bryson after he contacted the scrutiny body.
Finance Committee member and Sinn Fein MLA Michaela Boyle said: “He is a person of interest and we did put out the call for anyone who may have information to bring that forward to the committee.
“In terms of Mr Bryson’s letter to us we are not in the business of shutting doors on anybody with information; factual information, if it is a concern to this committee, should be brought forward.”
Mr Bryson was a high-profile Union flag protester who was convicted of taking part in unlawful public processions during a campaign against Belfast City Council’s decision in December 2012 to limit the number of days the flag flies from the city hall.
Nama is the “bad bank” set up by the Irish government to clear property loans from bailed-out lenders.
It and all private firms involved in the Northern Ireland assets sale have denied wrongdoing.
Nama sold the portfolio to US firm Cerberus last year.
Allegations were levelled in the Dail recently by Independent TD Mick Wallace.
Using parliamentary privilege, Mr Wallace alleged that £7 million in an Isle of Man account linked to the deal was “reportedly earmarked for a Northern Ireland politician or political party”.
A lawyer involved has denied the money was intended for a politician or relative of a politician.
The committee said it would send Mr Bryson its terms of reference. It is constrained by criminal investigations into the affair.
