A NIGHTCLUB waiter was yesterday sentenced to eight years' jail for trafficking in more than 260 grams of heroin. Tse Wai-loy, 29, had pleaded guilty before Deputy Judge Daniell in the High Court to two counts of trafficking in a dangerous drug. Prosecutor Christina Ma said Tse was intercepted by patrolling police at 3 pm on December 15, 1992, in Shanghai Street, Kowloon. A packet containing 147 grams of heroin was found on him. A further 119 grams of the drug was found at his home nearby. Under caution, he said he was a courier for a man called Sai Mou. Defence counsel Richard Wong said in mitigation Tse had been a drug addict since 1988. He could not finance his habit on his income as a nightclub captain. He decided to take up an offer to act as a courier in exchange for the promise of cheaper drugs.
