An auxiliary policeman was jailed for two years and three months yesterday for indecently assaulting two young girls. In the District Court, Deputy Judge Alan Wright told Lai Tak-chi, 27, the offences were serious because he had abused and exploited his position as a policeman. Lai was found guilty on six charges of indecent assault and one of perverting the course of justice. He had denied all the charges. Judge Wright said an immediate custodial sentence was appropriate because the offences were not committed on the spur of the moment. The court heard that one of the victims, a 14-year-old girl described by the judge as 'slow-witted', called the police on April 8 last year to report a stolen wallet. Lai, who went with a colleague to the girl's Sha Tin home, noted down her personal details, prosecutor Anna Lai said. A few days later, the girl received a call from Lai who said he was coming to visit her. When he arrived, he asked the victim to go into her bedroom, where he took off her trousers and indecently assaulted her. In mid-May, the defendant invited the victim out for a drive and indecently assaulted her in the car. In June, Lai was invited to go with the victim to her friend's home in Kowloon City and the defendant indecently assaulted her again. Lai was also convicted of indecently assaulting another 14-year-old girl in November and December last year. The girl was introduced to him by a friend and he molested her on three occasions. The defendant was found guilty of asking a third girl to give false information to the police, which amounted to perverting the course of justice. Defence barrister Wong Man-kit told the judge the offences were out of character, and said Lai's wife was now three months pregnant. Judge Wright said he had considered Lai's previous good record before passing sentence.
