Two mainlanders said to have been involved in a race-fixing scam with jockey Stanley Chin Kin-ming talked of having him killed or severely injured for unsuccessfully rigging a race, a court heard yesterday. Villa owner Jimmy Chan Moon-shing told the District Court his mainland friends became angry and demanded an explanation from Chin and his girlfriend, Denise Yeung Ka-yee, for failing to ensure the desired outcome of a race on January 27, 1996, at Sha Tin. When questioned by defence barrister Ian Lloyd, Chan admitted his friends had told him that they would arrange to have Chin killed or injured so he could not ride again unless he came up with a satisfactory explanation for losing the race. Chan, 53, is serving a 15-month jail term after pleading guilty to conspiracy to cheat at gambling. He told the court that at the end of 1995, two mainland friends asked him to approach Chin for tips. The group had several meetings in January 1996, during which Chin was said to have asked for $300,000 to fix a race. The money was deposited into Yeung's bank account and Yeung supplied Chan with the horse numbers to bet on, the court heard. Chan said he had placed $100,000 with an illegal bookmaker and another $100,000 with the then Royal Hong Kong Jockey Club. His mainland friends had placed about $500,000 in bets. But they had all lost. The next day, the parties met in Shenzhen, where Chin claimed his horse, which was supposed to win, stumbled and could not catch up, the court heard. Chin, 25, and Yeung, 28, have denied a charge of conspiracy to cheat at gambling in relation to the race on January 27. Chin has also denied another charge relating to a race on March 30, 1996, and charges of offering or accepting an advantage. The trial continues before Judge Peter Line.
