A garda investigation is under way following the death of a 48-year-old man in Co Wexford.
The body of John Lawlor was discovered by gardaí at the house where he lived in Courtown shortly before midnight last night.
It is understood he sustained a stab wound.
A second man, who was treated in hospital, is being questioned at Enniscorthy Garda Station.
Mr Lawlor, a father-of-three, was well known in the area having been a member of the local soccer club for many years.
Gardaí are investigating reports that a row took place in the house at Red Row, during which time Mr Lawlor received a fatal stab wound.
The scene remained sealed off for most of the day as garda forensic experts carried out examinations.
Another man, who was known to the deceased, was injured. He was taken to Wexford General Hospital but discharged this afternoon.
He was then arrested under Section 4 of the Criminal Justice Act and brought to Enniscorthy Garda station for questioning in relation to the death of Mr Lawlor.
At this stage, gardaí are not looking for anyone else in connection with the incident.
A post mortem examination on the body of Mr Lawlor is due to be carried out at Waterford Regional Hospital tomorrow.
