SIXTEEN police officers appeared in court yesterday in connection with allegations of illegal gambling, conspiracy to rob, theft and indecent assault. One constable was ordered to begin serving a three-month jail sentence after losing his appeal against a theft conviction. Three other officers faced allegations of plotting to rob a fruit shop when they made their first appearance at North Kowloon Court. Senior Detective Constable Ng Chi-wai, 39, Detective Constable Ng Yuk, 40, and Constable Woo Lai-wing, 33, were not called on to enter a plea. Ng Chi-wai, from the identification bureau, Ng Yuk, from the criminal investigation unit of Shamshuipo Police Station, and Woo, from Hunghom uniform branch, are alleged to have conspired together in an attempt to rob a fruit shop in Causeway Bay, between September 29 and October 1. The court heard the arrests followed an undercover operation in which their movements were monitored by other police officers. Imitation firearms, knives and wires were said to have been found at Shamshuipo police station on Sunday when the men were arrested by the Organised Crime and Triad Bureau. The trio, having been with the force between 10 and 22 years, have been suspended from duty. Magistrate Mary Yuen adjourned the case and remanded them in custody until October 12 for further inquiries to be made. In a separate hearing, 11 constables appeared at San Po Kong Court charged with gambling in an illegal establishment. The officers, aged between 24 and 42, were arrested inside a Kowloon City apartment in the early hours of September 30 during a joint operation by the Independent Commission Against Corruption and the Kowloon West regional crime unit. The 11, together with four other men found on the premises, pleaded not guilty to the single charge. One of the civilians, 26-year-old salesman Cheung Wing-kwong, denied a further charge of permitting the premises to be operated as a gambling establishment. Their trial was fixed for January 16 next year. Constable Lai Po-keung, 24, was remanded in ICAC custody. The others were granted bail of $2,000. Two officers also appeared at the High Court to appeal against convictions. Constable Chan Ho-lun, 25, was jailed for three months after he lost his appeal against a conviction for stealing $100 from a university student. The officer took the money after finding the victim, a homosexual, inside a public toilet in Lan Kwai Fong in October last year, and telling him he could be arrested for loitering. Chan had been on bail pending the result of the appeal. And Constable Mok Wai-wo, launched his appeal against a conviction for indecently assaulting a woman suspected of being in possession of dangerous drugs. His barrister, Christopher Grounds, called for a re-trial, claiming the magistrate who found Mok guilty had failed to properly consider inconsistencies in the prosecution case. Judgment was reserved to a later date.
