LEADING racing trainer Eddie Lo Kwok-chow was acquitted in Eastern Court of three drug-related offences yesterday when the Crown offered no evidence against him. His friend Tina Hui Mei-ling, 32, also walked free from court after she was acquitted of similar charges. It is believed the move followed strong criticism by Magistrate Fergal Sweeney and defence counsel Kevin Egan of the Legal Department during a hearing on February 16. The Legal Department was criticised over a total of five charges brought against Ms Hui and Lo after police and prosecutors were said to have viewed home video tapes seized in a raid on Lo's home on October 8. The evidence was said to be tenuous and the prosecution was described as having a ''very good imagination''. Yesterday, before Magistrate Jonathan Acton-Bond, prosecutor Michael Arthur offered no evidence on the five charges. Lo, 36, and Ms Hui were acquitted of a joint charge of trafficking in a dangerous drug and a joint charge of possessing a pipe fit and intended for smoking a dangerous drug. Lo had also faced a charge of possessing a pipe for drug smoking. Ms Hui was also acquitted of two counts of smoking a dangerous drug. However, Lo still faces four other charges. Earlier, Lo had pleaded not guilty to wilfully obstructing a police officer in his flat at Race Course Mansion, Sha Tin. He also denies two counts of possession of 0.44 grams of cocaine and 2.08 grams of a resinous substance containing 0.04 grams of cannabis. He also denies possession of equipment fit and intended for smoking a dangerous drug: a brush, a spoon, a straw and a pair of scissors. All the offences allegedly took place on October 4 last year. The case was adjourned and a new trial date has been fixed for August 15. Mr Egan claimed police did not have a search warrant when they raided Lo's home. He also said he would object to the admissibility of evidence based on the six video tapes seized. Lo's bail of $2,000 cash was extended.
