Gardaí say they are investigating all of the circumstances around the fatal stabbing of a 63-year-old Dublin man.
He was attacked at a house in Crumlin last night.
The incident happened on Rutland Grove at around 8 o'clock last night.
A 63-year-old man was found injured after gardaí were called to the house.
He was rushed to St James' Hospital where it is believed he was a staff member, but was later pronounced dead.
A man in his 30s was arrested in Blanchardstown and taken to Crumlin Garda Station.
A motive for the attack is still unclear, and detectives at Sundrive Road are appealing for information.
