A married police detective was jailed for seven years yesterday for raping an 18-year-old woman who had come to his house for help downloading games on to a hand-held games console. Choi Chai-him, 33, formerly attached to the crime unit of Sham Shui Po police station and currently suspended from the force, was found guilty of a single charge of rape by a five-to-two majority decision of a Court of First Instance jury. The jury had rejected Choi's claim that the woman consented to having sex with him at his home at the West Kowloon Disciplined Services Quarters in Tai Kok Tsui on February 27 last year. Choi and his victim had been conversing on the internet for two or three years before the incident, which took place on their first face-to-face meeting. Sentencing Choi to a lengthy jail term, Mr Justice Louis Tong Po-sun said the victim decided to visit the detective's house alone because she trusted him as a police officer. Mr Justice Tong said the incident had been traumatic for the victim, who faced further embarrassment having to give details of the event in court. Young people needed to be more cautious when meeting people they had got to know through the internet, the judge said. Parents and schools had a role to play in teaching young people about such dangers. Choi had invited his victim to his house on the promise of teaching her how to download games on to her PlayStation Portable games console. After putting some games on the console he had begun touching her. Senior public prosecutor Jasmine Ching Wai-ming had previously detailed how Choi refused the woman's demands to stop and prevented her from leaving. Ms Ching said he then took the woman to the master bedroom and raped her. The woman reported the incident to Sham Shui Po police station and Choi was arrested the same day.
