TWO robbers were severely beaten by six Vietnamese men and left to die in a New Territories container yard, the High Court heard yesterday. All six defendants have pleaded not guilty to murder. The defendants are on trial for the murder of Hoang Truong Giang, 19, and Do Viet Hieu, 28, before Mr Justice Stuart-Moore and a jury. They are Nguyen Tien Hao, 25, Vu Van Tuan, 18, Vu Hon Son, 29, Nguyen Huu Qui, 29, Duong Van Hoang, 20, and Tran Van Quang, 23. Hoang and Do died on September 19 last year at the Yau Shun container yard in Tai Lam Chung, New Territories. Senior Crown Counsel Chris Coghlan said four men were watching television in the container yard when the robbers struck. The six defendants all worked and lived in the yard. On the night of September 18 last year, one of the defendants, Duong, was tied up and robbed while leaving the yard. Counsel said one of the robbers who had been given immunity from prosecution would testify that he and his gang entered the container yard, held the workers watching television at knifepoint, tied them up and robbed them. Meanwhile Duong, who had managed to free himself, alerted the five other defendants in another part of the yard about the robbery. The defendants attacked the robbers, the court heard. The witness saw the victims beaten over their heads with an iron bar and then tied up by the defendants, counsel said. An argument broke out between the robbers and the defendants and metal container hooks were allegedly hurled at the robbers. Two of them managed to escape, but the other two were beaten and left to die, Mr Coghlan said. One of them was found inside the yard at 2.20 am still alive, but he died before arrival at hospital. It is not known precisely when the second robber died. The two died of mutiple injuries. Police arrested Nguyen Tien Hao at the yard two days later. Nguyen maintained he had left the scene after hitting one of the robbers with a fork. On September 23, the five other defendants were arrested at Lok Ma Chau by border control police, while waiting to cross into China. Mr Coghlan said that since they looked different, they stood out from the crowd of travellers to China. Vu Van Tuan said he had armed himself with a bottle and moved a container to dislodge a robber. He claimed he then ran away. Vu Hon Son said he hit the victims a few times and then left. Nguyen Huu Qui said he picked up a piece of wood and hit one of the robbers six times, the court heard. Duong had claimed he had armed himself with stones while joining the chase, but had not hit anyone. Tran said he had wielded an iron bar during the fight and chased one of the robbers, counsel said. The hearing continues.
