A man has been arrested as part of a murder investigation after a 32-year-old man died following a stabbing in Tallaght in Dublin.

James Humphries sustained fatal stab wounds after a row broke out in a house in Kiltalown Way at around 6.40pm yesterday.

He was taken to Tallaght Hospital, but was pronounced dead just after 7pm.

The father-of-one was originally from Glenshane in Tallaght, but had lived in Birmingham with his mother and three brothers for a time before moving back to Ireland.

He was in the house where the stabbing occurred with four other people to watch the All-Ireland Football final.

A man, aged in his 30s, was arrested at the scene and taken to Tallaght Garda Station.

He can be detained for up to 24 hours.

The house remains sealed off.

Detectives are seeking to interview all the people who were in the house when the attack took place.

They are trying to establish a motive for the attack, but believe alcohol was a contributory factor.

They have appealed for anyone with information to contact them.
