Gardai are continuing to question an 18-year-old over the fatal stabbing of a man at a north Dublin halting site.
Wesley Mooney (33) was stabbed to death during an attack in Dunsink Lane in Finglas the early hours of yesterday.
The victim, who was previously convicted for threatening to kill his former partner and their child, suffered one knife wound.
Emergency services rushed to the scene but, despite the efforts of paramedics, Mooney was pronounced dead a short time later.
A teenager was arrested at the scene, and detectives from Finglas Garda Station were still questioning him last night.
Mooney did not live at the halting site, and gardai are investigating whether he was disturbed by someone who did.
Locals said they heard no argument or row at the time of the incident, and only became aware of what had happened when emergency services arrived.
The victim lived at nearby Abbotstown Drive, where his family told the Herald yesterday that they were not aware of the circumstances surrounding his death.
"We know as much as the gardai and we don't think they know what happened either," said one man who was being comforted by family and friends at the house.
Mooney's body was removed from the scene yesterday afternoon, and a post-mortem was carried out last night.
The results will determine which direction the Garda investigation takes. Mooney was known to gardai, but mainly for motoring and public order offences.
He received a suspended sentence last February at Blanchardstown District Court where he pleaded guilty to possession of a claw hammer and threatening and abusive behaviour.
In 2008, he received a suspended sentence after he pleaded guilty to threatening to kill his former partner and their 14-month-old child because he was not allowed access.
He pulled what appeared to be a gun from a sock and pointed it at his partner, Kim Murphy, at her Clondalkin home, asking her if she wanted him to "put the three of us asleep together".
The court heard the relationship between Mooney and Ms Murphy had ended four months previously.
Mooney also pleaded guilty to acting as a lookout during a robbery at Terry Rogers Bookmakers on Glasnevin Avenue on August 24, 2010 while he was on bail.
Judge Patricia Ryan sentenced him to six years for both offences at Dublin Circuit Criminal Court but suspended it on strict conditions.
