A man has been found dead in a street following a suspected stabbing.
The body was discovered by a road in the Ballymun area of north Dublin in the early hours.
Gardai are treating the death as suspicious.
It is understood a house party had taken place nearby on Wednesday night.
The man's body remained on the street pending a forensic inspection of the scene.
The dead man was in his late 30s, gardai said.
His killing is being linked to an incident at a house on St Joseph's Way.
Two other men, one in his 20s and one in his 30s, and a woman in her 20s were injured in the attack and treated in the Mater Hospital.
A garda spokesman said two men in their 20s have been arrested and are being held under section 4 of the Criminal Justice Act 1984 at Ballymun Garda Station.
