One of the men being questioned about a fatal stabbing in Dublin has been released from garda custody.
22-year-old Shane O'Connor was found seriously injured on St Donagh's Road in Donaghmede on the morning of 29 October.
He was taken to Beaumont Hospital but was pronounced dead a short time later.
Another man in his mid-20s, who was arrested last night, is still being held at Coolock Garda Station.
