A judge warned yesterday of the 'untold damage' if police had not caught a drug dealer selling 1.4 kilograms of 'ice'. Deputy Judge Colin Jackson sentenced Wong Wai-lun to 24 years' jail for dealing in the designer drug. 'If the police had not seized this, it would have done untold damage on the streets,' Deputy Judge Jackson said. Police stopped Wong, 30, as he was leaving a Nathan Road flat on January 16. They found 95 grams of heroin in his pocket, the High Court heard. The ice and 500 grams of heroin were found in the flat. Wong, a drug addict, denied he was a drug dealer, but was found guilty by a jury.
