It has emerged that Gardaí are investigating claims made by independent TD Mick Wallace about the conduct of NAMA.

Gardaí are looking into allegations that a developer paid €30,000 in cash to a NAMA official, in order to get out of the agency's control.

Earlier this year Wallace claimed a developer had paid two instalments of e15,000 in cash in order to exit the agency.

The agency has denied any wrongdoing in connection to the incident, or in its handling of the sale of Northern Ireland loans.

Nama CEO, Brendan McDonagh, denies the allegation about a developer buying their way out, and says the company who allegedly made the payment remain in Nama.

“The alleged company that is supposed to have paid this money for exiting Nama, is still in Nama, owes all its full debts to Nama Has had no debt write off from Nama. So whether the money was paid or not is for the gards to investigate,” he told the Oireachtas Public Accounts Committee today.

“But all I can say is the company mentioned to us is still with us,” he said.

“Whether there was a payment made or not that is being investigated by the gardai.

“The premise of the payment was they paid 15 grand, according to Deputy Wallace, before they got out, and then paid 15 grand when they got out.

“I don’t think people would pay 15 grand when they’re still stuck in Nama,” he added.

Meanwhile, The North's first minister Peter Robinson says he will attend a Stormont committee to address claims that he was due to benefit from money left in an Isle of Man bank account.

Mr Robinson denies the claims made by Loyalist blogger Jamie Bryson, who may still be called to give evidence at the Public Accounts Committee.

However NAMA itself is still refusing to attend the Stormont committee investigating the sale of its Northern Irish loans.

PAC chairman John McGuinness says NAMA would have "nothing to lose" by answering questions from MLAs in Belfast.
