A veteran police officer who was recovering after being shot in an Aberdeen underpass last month - allegedly by an off-duty constable - died early yesterday after collapsing on a jogging track. Wong Siu-pang, a 44-year-old station sergeant with the Hong Kong Island section of the Police Tactical Unit, died in hospital just after 4am, about eight hours after collapsing on a track at Wan Chai Sports Ground. Wong had been on sick leave since he was shot in the thigh on September 6 after an emotionally disturbed constable allegedly grabbed another officer's revolver during a scuffle on the stairway of the pedestrian subway in Aberdeen. Wong was discharged from Queen Mary Hospital on September 14 and was due to return to work on October 19. According to a police source, Wong suffered from heart disease and high blood pressure. 'It's an unfortunate incident. We are saddened and shocked over his death,' a police spokesman said. 'The police force will provide assistance to his family.' The spokesman added the police would offer a HK$15,000 ex gratia payment to Wong's family. Wong was jogging with colleagues at the sports ground in Tonnochy Road at 8.15pm on Tuesday when he complained of feeling dizzy and collapsed. He was taken unconscious to Ruttonjee Hospital, where he was declared dead by doctors yesterday morning. Police said their initial investigation had found nothing suspicious, but they were still looking into the cause of Wong's death. Wong joined the police force in 1981 and lived with his family in Wong Tai Sin. The Aberdeen shooting came six months after the police force was shocked by a shoot-out in a Tsim Sha Tsui underpass, also involving an off-duty officer, which left two constables dead.
