The owner of a Randalstown Chinese restaurant who was murdered in front of his wife has been named by police as Nelson Cheung.
The 65-year-old father of four was killed after two vehicles forced his car off the road in a remote area of Northern Ireland.
It is believed his throat was cut.
PSNI Detective Chief Inspector Eamonn Corrigan said: “Mr Cheung was a well-liked and well-known man who ran a Chinese restaurant in Randalstown.
“He was a father of four and husband to Mrs Winnie Cheung, who was injured during the attack on the Caddy Road.”
Mr Cheung had been travelling home from his Co Antrim business shortly after midnight on Thursday when he was stabbed after being intercepted by two vehicles on a rural road. He was also robbed.
He was a well-established trader in Randalstown, running the Double Value restaurant on the town’s main street, and his knife attack death has sent shockwaves through the community, councillors said.
Mrs Cheung, who was also in the car but managed to escape, has been treated in hospital for knife wounds.
She has since been discharged although is still reeling from the trauma of the attack, police said.
Mr Corrigan added: “Mrs Cheung has been released from hospital but is understandably anguished following the murder of her husband.
“My thoughts and the thoughts of my investigative team are with the Cheung family.”
Detectives last night released unconditionally a woman aged 31 and a 29-year-old man who were arrested in connection with the investigation.
A 30-year-old man remains in police custody.
Police do not believe the killing was racially motivated.
The PSNI have renewed appeals for anyone with information to come forward.
