Three men were jailed yesterday for arranging bribes from people who wanted to be members of the Jockey Club, in a 2009 scam. Full club member Robert Ng Ka-ki - also known as Robert Woo - was sentenced to two-and-a-half years after being convicted this month of defrauding the Jockey Club. He claimed falsely that he knew various applicants for membership. Alan Lam Wai-chee, a 60-year-old clerk, was sentenced to two years in prison after being convicted of aiding and abetting an agent in accepting an advantage. Construction worker Billy Tang Kang-chung, 50, was given a three-and-a-half year jail term after being convicted of three counts of money laundering. Ng got fellow members to act for the applicants as seconders, proposers and supporters, roles that are necessary in recommending outsiders to the prestigious racing club. He was caught when - working through Lam - he asked for HK$250,000 from two undercover agents from the Independent Commission Against Corruption, who pretended to be red-wine traders interested in joining the club. Tang helped a minibus and taxi merchant, Chan Yuet-ming, arrange for his son to obtain the highly sought after membership. Chan paid a total of HK$1.25 million in the process. Judge Joseph Yau Chi-lap said in District Court yesterday that Ng's jail sentence had been mitigated because he had pleaded guilty, and because of his record of charitable works. The judge said that Hong Kong was one of the least corrupt cities in the world, and that deterrent sentences were needed for such corruption cases. 'We are proud of our achievement and cannot allow a small group of unscrupulous individuals to undermine our success and the reputation we have built up,' he said.
