Police say they are following a definite line of inquiry following the killing of a man in south Belfast early yesterday .
A PSNI patrol was called to a disturbance at an apartment at Hampton Drive in the Annadale area of the city at about 3am. There they found a man suffering from serious knife wounds. Two other men also had stab wounds.
The seriously injured man, understood to be a Chinese national and a restaurant worker, died from his wounds despite first aid on the spot.
The other men, also Chinese, were taken to hospital, where their wounds were said not to be life-threatening. They were arrested there in connection with the killing.
The police have said they do not believe the incident was linked to either a sectarian or racial motive.
SDLP Assembly member Carmel Hanna said she was concerned about the growing culture of violence in her area.
"There has been a spate of violence in south Belfast in recent years, and the community must stand against those who perpetrate these awful crimes," she said.
