A TEAM of Hong Kong police officers are in Fuzhou interviewing a suspect in connection with the killing and dismemberment of a 29-year-old Cheng Sau-ling in Western last month. The man, 29, was arrested at his parents' home by Fujian Public Security Bureau last Friday night. A police source said the officers would remain in Fuzhou for a few days. China is likely to deport the suspect through the land border at Lok Ma Chau or Lowu, because Hong Kong and China do not have an extradition treaty. It is understood the man came to Hong Kong this year from the United States, and lived in Queen's Road West. The Central restaurant waitress was reported missing by her husband on July 31, the day police found a woman's torso floating off Western waterfront. More body parts surfaced in the water over the next few days. On Tuesday, detectives retrieved a suitcase from the seabed in Belcher Bay near the reclamation site. It is being examined to confirm if it is connected to the killing.
