A policeman suspended from duty after the drug ketamine was found in his locker in Yau Ma Tei police station plunged to his death from a public housing block in Sau Mau Ping yesterday. Constable Chan Chun-wing, 23, who was attached to the station's patrol sub-unit, jumped from Hei Wah House, Lok Wah South Estate. He was declared dead outside the block. Chan was required to report to Sau Mau Ping police station daily during an investigation into his case. Police refused to comment on whether his death was linked to the case. Chan, who joined the force in 1998, was arrested on December 2 after ketamine tablets were found in his locker following his collapse in the street from a suspected drug overdose. Divisional commander Superintendent Wong Wai-fung said he was saddened by the death but added the force had provided sufficient channels for the officer to seek help. The apparent suicide was the first involving a police officer this year. Last year, eight police officers committed suicide. Earlier yesterday, a 24-year-old woman surnamed Tang was found after apparently leaping from a building on the Jat Min Estate at Sha Tin. And a woman, 27, jumped to her death from the Sunbeam Centre in Shing Yip Street, Kwun Tong. A woman police negotiator successfully persuaded the 27-year-old wife of a police officer to abandon her suicide attempt at the Kwai Chung Police Married Quarters last night. The woman slashed her left wrist with a knife after a dispute with her husband before running up to the roof of the 23-storey building. She was talked down after 40 minutes.
