A Dublin man has been charged with IRA membership at an out-of-hours sitting of the Special Criminal Court.

Robert Day, 54, from Cabra, Dublin 7 was charged at the non-jury court this evening with membership of an unlawful organisation within the State styling itself as the Irish Republican Army, otherwise Oglaigh na hÉireann, otherwise the IRA on 9 October 2015.

Detective Garda Leanna Cruise told the three-judge court she arrested Mr Day under section 30 of the Offences Against the State Act at 2.15pm at Londonbridge Road, Ballsbridge, Dublin 4.

She said she showed Mr Day her official identification, explained to him the reason for his arrest and cautioned him, to which he made no reply,

Det Gda Cruise said she transported Mr Day to Irishtown Garda Station and on to the Special Criminal Court, where she showed him a copy of the original charge sheet to which his reply was "no comment".

Wearing an orange Glasgow Celtic soccer jersey, Mr Day made no reaction when asked to stand up by the registrar of the Special Criminal Court.

When asked was he Robert Day, he said "I am" and the registrar proceeded to read the charge to him.

Ms Justice Margaret Heneghan, presiding alongside Judge Ann Ryan and Judge Flann Brennan, remanded Mr Day in custody until Thursday next when an application for bail is expected to be made.

Barrister Mark Lynam, for Mr Day, consented to the remand order.

Mr Lynam said he was reserving his position in respect of lawfullness of the arrest.
