Gardaí are questioning a man in his 40s following the fatal stabbing of another man in Co Tipperary, who died in hospital early this morning.
The incident happened at around 11.30pm on Saturday night in an apartment in Carrick-on-Suir, where three men and a woman had gathered.
A dispute arose between two of the men and one sustained a serious stab injury. Emergency services were alerted and the victim was brought by ambulance to University Hospital Waterford.
However, the man, who was also in his 40s, died as a result of his injuries in the early hours of this morning.
Gardaí have not released the man's name, but it is understood he was originally from eastern Europe and had been living on his own in the apartment for some time.
A post-mortem examination is expected to take place later today.
Gardaí arrested a man yesterday afternoon in the Carrick-on-Suir area and he has been held at Clonmel Garda Station for questioning.
It is understood he is also originally from eastern Europe, had also been living in Carrick-on-Suir and was known to the deceased.

Anyone with information has been asked to contact Clonmel Garda Station, where an incident room has been set up, on 052-6177640 or any garda station.
