A constable whose driving caused a crash which killed his girlfriend and who told other officers he had not been in the car was jailed for 14 months yesterday. Chu Chi-kong, 28, was also suspended from driving for two years by Sha Tin magistrate Loh Lai-kuen after being found guilty of perverting the course of public justice and reckless driving causing death. He had denied both charges. The court had heard how Chu was driving girlfriend Shum Pui-fun, 21, and three other friends home in his four-seater car early on October 29 last year. After he ignored a red light, the vehicle collided with a minibus at the corner of Tai Chung Kiu Road and Sha Tin Rural Committee Road. Shum died of multiple injuries. Chu, who was off duty, told police he only arrived at the scene after his friends called him. Passenger Yau Lai-fong, 21, told officers she had been driving. At an earlier hearing, Yau was jailed for a month after she admitted lying. Barrister James Chandler, for Chu, said he would appeal against the sentence.
