A JUDGE had to abandon delivering a verdict on a policeman charged with robbery after the man collapsed in the dock yesterday. Judge Whaley was about to give his verdict in the District Court when Constable Wong Yung-keung, 26, crashed to the floor. His relatives wailed and shouted in court, claiming he was innocent. They also tried to rush the dock but were stopped by guards. In the middle of the confusion, Judge Whaley quietly left the court. Wong was helped up by the guards and taken back to the cells. The interruption lasted 15 minutes and the hearing resumed after relatives promised to calm down. William Stirling, defending Wong, asked the judge to adjourn proceedings because Wong needed medical treatment. He apologised on behalf of Wong's family. The judge said he understood and adjourned the case until Monday. Wong, Sergeant Tam Kin-yuen, 39, and Tam Shing-choi, 37, all denied robbery. The court heard businessman Lam Ching-hui was pounced on in a car-park lift on October 9 last year. The attackers demanded his watch and gold necklace, and then clubbed him on the side of the head. Minutes later someone tried to withdraw money from a cash machine using Mr Lam's Visa card. Fingerprints on the card matched Wong's, the court heard.
