Gardai have appealed for witnesses after two men died following a house gathering in Cork city on Christmas Day.

It is believed both men died as a result of drugs overdoses at the house in Rockgrove Terrace in the city.

Gardaí from Watercourse Road in Cork were first called to a house at Rockgrove Terrace off the Lower Glanmire Road near the city's railway station just before 1pm yesterday.

There had been a party ongoing at the house on Christmas Eve and throughout Christmas Day.

A 33-year-old man was pronounced dead at the house and his body was taken to Cork University Hospital.

Later yesterday evening a 32-year-old man was removed from the same house to the Mercy University Hospital.

He was in a critical condition and he died in the early hours of this morning.

A post-mortem examination was conducted this morning on the body of the first man.

The second post-mortem will be done tomorrow morning, but at this stage Gardaí are satisfied that both men died of drug overdoses, having taken a cocktail of drugs which included heroin and methadone.

Gardaí have traced 9 of the 10 other people who were at the party, and a search is continuing for the tenth.

They will prepare files for the coroners court in due course.
