A SOLICITOR'S clerk found in possession of more than two kilograms of heroin mixture was yesterday sentenced to 22 years' jail by the High Court. The sentence was imposed by Mr Justice Bewley on former policeman Tse Kam-yuen, who was found guilty by a jury of possession of dangerous drugs for trafficking and simple possession. Tse, 43, had denied both offences. During the trial, the court heard evidence called by Senior Crown Counsel Kevin Zervos that customs officers stopped a taxi in which Tse was a passenger. A total of 2,034 grams of heroin mixture were found in a bag he was carrying and on the floor of the taxi and a further 110 grams of a similar drugs were seized from his pocket. He did not give evidence in his defence. In mitigation, Niall Stirling said being a drug addict might have contributed to Tse's downfall and asked the court to give him a sentence as lenient as possible.
