A drug suspect was found dead after slipping out of a handcuff and fleeing the hospital ward where she was being guarded by two police officers, an inquest heard yesterday. Wong Wai-fong, 32, who was shackled to her bed, managed to free herself and escape from the Queen Elizabeth Hospital accident and emergency ward waiting room at about 4pm on July 17 last year. Coroner Michael Chan Pik-kiu heard that Wong was taken to hospital under the custody of police constables David Chan Wai-kuen and Candy Man Man-kin after falling unconscious in a lift in the Kowloon City Court building following an appearance on charges of possessing a dangerous drug. Constable Chan told the court Wong had said she wanted to go to the toilet so he left the room to ask Constable Man for help. Constable Man said that when she entered the room, Wong was missing and the handcuff originally fastened on her wrist remained locked to the bed. Constable Man said she had checked the lock of the handcuff and properly adjusted it around Wong's left wrist. About an hour after her disappearance, Wong's body was found on a road near her home in Shanghai Street, Mongkok, by an off-duty police officer. An ambulance was called but she was declared dead on her way to Kwong Wah Hospital. Police officers found two syringes in Wong's home near stairs leading to the roof of the building during a search later that day, the court heard. An autopsy report said Wong probably died as a result of falling from a height. It said a small amount of morphine was found in Wong's body. The pathologist concluded Wong might have injected heroin before her death. A five-member jury is due to return its verdict today.
