Jason Flannery, aged in his early 40s, suffered fatal knife wounds in the violent argument, in which three other people also sustained injuries, one of them serious.
Gardaí believe that eight people were involved in the melee on St Joseph’s Way in Ballymun, north Dublin, and that a number of them were armed with knives and hurleys.
Gardaí were called to the scene at 4am. When they arrived, within minutes, from nearby Ballymun Garda station, they found the body of a man lying slumped on the ground, dead.
The scene was immediately sealed off and gardaí secured the area. They spoke to neighbours and people on the street in a bid to determine what happened. One man was arrested at the scene almost immediately, and a second man two hours later. Both were aged in their early 20s.
It is understood that Mr Flannery, a father of three, had held a party for one of his daughters who had received her Junior Cert results at their home in nearby Cairn Court.
In the early hours of yesterday morning neighbours had gone to the house and apparently complained about the noise levels.
Some sort of argument flared which escalated out of control and onto the streets, during which Mr Flannery received fatal injuries.
Three other people also sustained injuries, one of them serious. Two men, one in his 20s, the other in his 30s, and a female, aged in her 20s, were taken to the Mater Hospital. One of the men who sustained serious injuries is thought to be in a stable condition.
It is understood that gardaí have recovered weapons from the scene and they are being forensically examined.
Mr Flannery’s body remained on St Joseph’s Way pending the arrival of the State pathologist. A postmortem was carried out later.
Superintendent Paul Moran of Ballymun Garda station appealed to people who had any information in relation to the incident or who were in the area at the time to contact them.
“We are still at the very early stages of this investigation,” he said.
“We have two people arrested, one shortly after the incident at 4am and one at 6am. They are both in their early 20s. We understand there was an altercation on the street
itself between Cairn Court and St Joseph’s Way.”
The two men arrested are being questioned at Ballymun Garda station, under section 4 of the Criminal Justice Act.
Neighbours paid tribute to Mr Flannery: “He was very quiet,” said one woman. “He done no harm to nobody, minded own business, a lovely chap.”
