Gardaí are appealing for witnesses after a man in his 20s died in an apparent stabbing in west Dublin last night.
Shortly after 6pm, officers attended the scene of an incident at a house in Castlecurragh Heath, Mulhuddart.
They discovered a man in his 20s with apparent stab wounds.
He was treated by emergency services at the scene, but was pronounced dead a short time later.
His body has since been removed to the city mortuary at Whitehall, where a post-mortem examination is taking place.
Meanwhile, a man in his 40s has been arrested in connection with the incident.
He's being held at Finglas Garda Station under Section 4 of the Criminal Justice Act 1984.
Anyone with information about the incident is being asked to contact Blanchardstown Garda Station on 01-666-9000 or the Garda Confidential Line on 1800-666-111.
