The victim, 18-year-old Kwok Hin-ching, 18, died, according Prosecutor Patrick Loftus, after receiving multiple blunt-force injuries and cuts and being run over by a motor vehicle. Kwok was then left lying on the road until the police and an ambulance arrived.

Wong had been told prior to the assault that someone nicknamed “Tai Kau” from his faction had been attacked by members of a rival faction of Sun Yee On, Loftus said. He also said Wong was told Tai Kau’s attack had occurred two or three days before December 5 and that Tai Kau wanted revenge.

The evening of the attack, the unarmed Wong got into a car with people who were armed with sticks and knives before proceeding to Tseng Tau Tsuen, Loftus told the court. However, the vehicles soon left Tseng Tau Tsuen after seeing no one there, only to return later and find members of the rival faction waiting.

Wong’s car was attacked by those waiting, causing it to hit a metal barrier and a parked vehicle.

Wong saw an armed Chau Tsz hit a male, whom Wong did not know, and four others, two whom he knew, Loftus said.

“The defendant thought to go forward to help but members of the Tseng Tau Tsuen rival faction arrived unexpectedly and the defendant fled, having injured himself getting out of the vehicle,” Loftus said.

Wong has claimed that he did not know the purpose of going to Tseng Tau Tsuen when he entered the car with the other armed individuals.

But Loftus said Wong had been in a “joint enterprise” with members of his triad faction with the “full knowledge” that others had weapons, including knives and poles, and that they were going to harm someone.

Wong’s lawyer, David Boynton, said Wong, who assembled platforms and stalls for a living, was deeply remorseful and that he had spent a period in psychiatric care after contemplating suicide.

Madam Justice Clare-Marie Beeson adjourned Wong’s case to February 25 for sentencing.
