Man arrested in connection with Kenneth O’Brien murder released
A man in his 30s who was arrested five days ago in connection with the murder and dismemberment of Kenneth O’Brien has been released without charge.
A file will now be prepared for the Director of Public Prosecutions.
A second man, aged in his 50s, remains in custody.
Mr O'Brien (33) - originally from Ballyfermot in Dublin - was fatally shot once in the head and his body dismembered. His torso was placed in a suitcase and dumped in the Grand Canal at Ardclough in Co Kildare.
Additional body parts were later found in the canal near Sallins, Co Kildare.
Earlier in the week gardai found an imitation firearm and a fake hand grenade during a search of a house.
Members of the garda technical bureau searched the house in Finglas in north Dublin.
Sources said that an imitation firearm and fake grenade were found during the search and gardai have been investigating links to dissident republicanism.
The army bomb disposal unit was called to the property, but the grenade was quickly declared safe.
