A man whom Gardaí believe to be a senior member of the IRA has been denied bail amid concerns for the safety of a prosecution witness.

Kevin Braney of Glenshane in Tallaght, Dublin 24 is alleged to have been present when the man was threatened if he didn't drop a legal action.

He, along with co-accused Ciaran Maguire from Kippure Park in Finglas, is charged with membership of an unlawful organisation.

Chief Superintendent Thomas Maguire from the Special Detective Unit told the court he was in possession of confidential information that Kevin Braney was a senior figure in the IRA and that it was his belief the witness would be injured or killed if he was released.

Tony McGillicuddy, on behalf of Mr Braney, said his client was entitled to the presumption of innocence and pointed out there was no evidence to back up his claims.

But the court said it was satisfied the potential interference with witnesses was a real concern and refused bail.
