Three Hong Kong apprentice jockeys were charged with misconduct and fined a total of $15,000 yesterday after stewards concluded an inquiry into a bullying incident on a school bus last month. Stewards acted on a report from Mark Tung, headmaster of the Apprentice Jockeys' School, regarding the conduct of a number of apprentices on the bus on the way home after the meeting at Happy Valley on December 22. Paul Lo Pak-hin was charged with misconduct for harassment of trainee Michael Law Chi-kwan, who is attached to the David Hayes stable. In a carefully worded report, chief stipendiary steward Jamie Stier said the harassment included 'physical contact being made in the vicinity of Law's head' - steward-speak for a straight right to the chin. The blow caused Law's head to hit the bus window. Lo was fined $10,000, with stewards stipulating that the money must be paid by the apprentice, and not by someone else on his behalf. Way Leung Ming-wai was found by stewards 'to have contributed to the harassment' of Law. He was also charged with misconduct under Jockey Club rule 57(8), found guilty and fined $3,000 with a similar stipulation. The most junior apprentice involved in the incident was Terry Wong Chi-wai, who is attached to the John Moore stable. Wong was charged along identical lines to Leung, but fined only $2,000. A fourth apprentice, trainee Brian Liu Ka-wa, escaped with a reminder that he must 'conduct himself appropriately at all times'. Martin Knibbs, the steward most involved with training and educating Hong Kong's next generation of jockeys, said there was nothing more to the story than what appeared in the club's statement. 'I think it was just a case of boys being boys,' Knibbs said.
