The president of the Sinn Fein party, Gerry Adams, says he knows the alleged name of a man accused of raping Paudie McGahon.
Mr McGahon's case was featured on a BBC documentary last night. He says he was raped by an IRA member in the early 1990s.
Mr McGahon says he brought the allegations to a Sinn Féin representative in 2002 - but was then interrogated by a so-called 'kangaroo court', similar to the case of Mairia Cahill.
Reaction to the allegations has been strong across the social and political spectrum.
Mr Adams also said that if the kangaroo court scenario happened, it was totally wrong.
He told the Pat Kenny Show here on Newstalk that all the information he has has been given to the gardaí.
