INDEPENDENT TD Michael Lowry is remaining silent about the garda investigation into a tape recording of a phone conversation between him and a land agent.
During the phone call, he pleaded with Kevin Phelan not to tell the Moriarty Tribunal of a payment of either stg£200,000 or stg£250,000 he had made to him.
Justice Minister Alan Shatter confirmed that the gardai were aware of the tape recording and were giving it attention.
But a spokeswoman for Mr Lowry said he was not releasing any statement in response.
In the Moriarty Tribunal report, Mr Lowry said he paid Mr Phelan more than stg£60,000 through a company called Vineacre to ensure he had had no future claim to a land project in Wigan.
But in the taped conversation from 2004, Mr Lowry constantly referred to a sum of either stg£200,00 or stg£250,000 paid to Mr Phelan.
