A suspect in a short-piling case jumped to his death two days after Independent Commission Against Corruption officers interrogated him for 4.5 hours and accompanied him home afterwards, an inquest heard yesterday. A Coroner's Court jury heard that Leung Cho-choi, 46, looked frightened and weak when he arrived home with senior investigator Chan Yun-tin and assistant investigator See Chiu-kwan after midnight on March 3. The officers took the construction worker from his Yuen Long workplace to the ICAC's head office in Central on March 2. Leung was the 21st person arrested in connection with a short-piling investigation, the court was told. After officers Chan and See finished asking Leung 96 questions, they arranged a car and driver and accompanied him home. Widow Chow Kam-mui, 41, said when Leung arrived he was frightened, pale and unable to speak, but in good health. Early on March 4, Leung was found lying on the ground at a construction site near his home. Police suspect he jumped from the building's fifth floor. He died from multiple injuries at the scene. Officer Chan testified that because it was very late and Leung, who claimed to be dizzy, was not familiar with Hong Kong Island, he was driven to his Tuen Mun flat in the interests of safety. He said he and his colleagues did not talk to Leung during the 35-minute trip, except to ask directions. When asked by Coroner's Officer Winston Chan whether Leung, who had not eaten during the interrogation, was fit for a 4.5-hour interview with just one short rest, officer Chan said he only appeared to be more nervous than other suspects. But a video played in court showed Leung was so weak the officers had to support him in a lift in his building. Chief investigator Yang Yan-tak said it was an 'absolutely correct decision' to drive Leung home in the company of two investigating officers, adding such an arrangement was not rare. The Coroner's Officer then asked: 'As Leung was accompanied by two officers who had interviewed him, how can we be assured no interrogation was carried out during the trip?' Officer Yang replied: 'Without my permission, none of my subordinates would dare undergo interrogation which was completely in breach of rules. We only provided services to a suspect who felt uncomfortable. We have done better than what was required.' The jury heard officer Chan initially accompanied Leung to a bus stop but the pair were called back to the office as he forgot to formally arrest Leung, even though he had been treated as a suspect. Officer Yang admitted officer Chan was wrong in this regard. It also was revealed in court that Leung had been depressed on and off for more than 10 years, but his situation had improved after taking anti-depressants. In 1998, Leung tried to jump to his death and he saw a doctor two months before the interrogation when his situation again deteriorated. The jury is due to deliver its verdict today before Coroner William Lam.
