A major investigation is underway into the fatal assault of a father outside his north Dublin home just after midnight.
The man, aged in his 60s, is thought to have been stabbed and officers are investigating if the attack is linked to a local row.
The man was confronted by people in the front garden of his house on Dunsink Green, Finglas west, where a fight ensued.
His homicide follows the death of his son six years ago in a motorbike accident.
While his son was embroiled in a violent feud with a local gang boss, gardaí do not believe the father’s death is connected to gangland.
Garda sources stress it is very early in their investigations and that a case conference was ongoing this morning.
Emergency services were called to the area shortly before 12.30am.
They found a man on the ground and provided initial treatment before bringing him to Connolly Hospital Blanchardstown.
Surgeons were not able to save him and he was pronounced dead.
It is believed he suffered a number of stab wounds.
The house was sealed off by local gardaí, pending the arrival of the Garda Technical Bureau, which began a forensic examination outside the home this morning.
The Office of the State Pathologist was notified.
A full post mortem will provide further details on the injuries inflicted on the man and will inform the garda investigation.
Gardaí are conducting local inquiries and checking to see if any of the homes have cameras. In addition they are checking local streets and roads for camera footage.
At this early stage, gardaí suspect the attack may be linked to a local row. They will begin the process of trying to identify who was there, which in turn may give clues as to what it was about.
Investigating gardaí are appealing to anyone who may have witnessed the incident to come forward. They are particularly appealing to those with video footage and motorists who may have dashcam footage from the area at the time to contact them.
Anyone with information is asked to contact Finglas Garda Station at (01) 666 7500, the Garda Confidential Line at (1800) 666 111 or any Garda Station.
"Investigations are ongoing," a garda spokesperson said.
