A 32-YEAR-OLD woman hanged herself with her jacket in a Kwun Tong Court cell where she was held pending a drug addiction report, an inquest heard. A coroner's jury returned a verdict of death by suicide on Yeung Yu-king who was found to have traces of morphine in her blood. The cause of death was hanging. Police Constable Lui Lai-fung told Coroner Rodney Venning that on February 23 this year Yeung was in the cells attached to the court. Yeung, who had appeared in court on a charge of stealing $30 from her employer, was remanded by the magistrate for a drug addiction report. Constable Lui said Yeung was given her lunch at 1.10 pm but handed it back 25 minutes later uneaten, saying that she was not in the mood. The officer said that when she returned less than a minute later from discarding the lunch she found a black jacket tied around the bars of the cell and Yeung leaning against the door. ''I immediately opened the door and untied the knot on the jacket sleeve and shouted for help,'' Constable Lui said. She said Yeung had a faint pulse. She was taken to the United Christian Hospital where she died about an hour later. Her boyfriend, To Yun-keung, 36, a transport worker, denied that Yeung was using ''white powder'' before her appearance in court. He claimed she had given up her drug habit following an earlier conviction for drugs.
