A VISITOR from Taiwan was stabbed dead and three relatives seriously wounded when they were ambushed by a lone attacker as they walked home through fields in the New Territories, the High Court heard yesterday. Chung Ting-shen, 65, a teacher and former pastor from Taiwan, was killed after he tried to stop his attacker taking his watch. His sister, Chung Tim-wan, daughter Chung Yu-hsin, 22, also from Taiwan, and niece Poon Kam-fun, 27, were all badly hurt. Tang Koon-yin, 32, has denied one count of murder and three of wounding with intent. He is also alleged to have stolen Chung's watch. Chung had been staying with his sister at her home in a remote Yuen Long village. He was due to return to Taiwan two days later. Prosecutor Frederic Whitehouse, opening the Crown's case before Mr Justice Ryan and a jury, said the family was walking up a footpath from Castle Peak Road at about 8.30 pm on August 3, 1991, with two nieces, aged seven and eight, when they were attacked. Tang first attacked and robbed Chung, who had fallen some way behind the others, seizing his watch, said counsel. When Chung resisted he was stabbed repeatedly in the chest and stomach, causing injuries from which he died the next day. Chung's sister and daughter went back to see what was keeping him and both were stabbed, the elderly lady receiving three stab wounds in her chest and abdomen and the daughter one in her stomach. Ms Poon then heard the disturbance and walked back along the path. She stepped back to let a man riding a bicycle pass, but was stabbed in the chest. Tang was arrested nine days later after inquiries revealed he lived locally and often rode his bike in the area. The hearing continues.
