A man has been arrested after the death of a 25-year-old man in Tramore, Co Waterford.

Michael O'Dwyer, who is originally from Kilkenny city but had been living in Stoneyford in Co Kilkenny, was stabbed at a house in Seafield, Tramore, late last night.

It is believed Mr O'Dwyer was visiting a friend or friends and they had been together for most of yesterday.

Other residents in the estate said they heard what sounded like a party in the house.

Gardaí were called to the property at 11.30pm and Mr O'Dwyer was taken by ambulance to Waterford Regional Hospital where he died of his injuries shortly after 1am.

A 32-year-old man, who was believed to have been with the victim earlier in the day, was arrested in the vicinity of the property shortly after gardaí arrived.

The man, also from Co Kilkenny, is being held at Tramore Garda Station.

A number of other people who were in the house are also helping gardaí with their inquiries.

A post-mortem examination is being carried out by State Pathologist Dr Marie Cassidy.

Gardaí have appealed for information about the incident.
