A man has been added to the New South Wales Police Force's Most Wanted list over the murder of a Chinese national in Sydney last week.
Gongcheng Chen was found dead at his apartment block on Marion Street at Auburn early last Tuesday morning.
The 23-year-old from China had several stab wounds and a knife was found at the scene.
Neighbours had been woken by a loud and protracted argument beforehand.
Police believe several people were inside the unit at the time.
Detectives have now revealed the name of the murder suspect, Mr Chen's housemate, a 23-year-old man called Changjie Wang.
Police have issued a warrant for his arrest and his name has been added to the state's most wanted list.
The murdered man's family has made an emotional appeal for help to find his killer.
Gongcheng Chen's mother flew in from China last week.
The Chinese student's mother was in tears today as her daughter Chenghui Chen pleaded for help for the public.
"I'm so sad about my brother. If anyone has any information please contact the police," she said.
Changjie Wang has not been seen since the night of the attack and detectives believe members of the Chinese community may be harbouring him.
Detective Superintendent Phil Rogerson says the man has not been seen since the attack.
"If any person is harbouring this offender, he's committed a very serious offence and he will be dealt with," he said.
The accused is described as being of Asian appearance, 160cm tall, of average build with dark hair and a tattoo on his chest.
He also goes by the names of Jie Wang and Wang Changjie.
Strike Force Grantsdale has been formed to investigate the murder by detectives from Flemington Local Area Command with assistance from the State Crime Command's Homicide Squad.
Police say Chang Jie Wang is the seventh person on the state's Most Wanted list.
