A man will appear in court again next week charged in connection to the murder of Detective Garda Colm Horkan.
The officer died on Wednesday night in Castlerea, county Roscommon.
Stephen Silver of Aughaward, Foxford in county Mayo was brought before a special sitting of Castlerea District Court last night.
The 43-year-old made no reply when he was charged with the murder of 49-year-old Detective Garda Horkan.
The officers death followed a violent incident in Castlerea town on Wednesday.
Mr Silver kept his head down for much of the proceedings - but did say "unreal." and "I had no firearm".
His solicitor asked for all appropriate medical assessments be carried out - and free legal aid was granted.
He will appear again on Friday at Harristown District Court via video link, and has been remanded in custody.
Meanwhile
The Garda Chief Superintendent in Waterford Padraig Dunne says retired members and other emergency services are welcome to attend events at their local garda station on Sunday afternoon.
A minute's silence will be held outside all Garda stations at midday tomorrow, the flag will be flown at half-mast and gardai will parade outside in uniform.
