A smiling drug trafficker cuddled and kissed his infant son through the bars of the dock after being sentenced to 14 years in prison yesterday. Guards stood to one side and allowed 25-year-old Woo Wai-kuen to play with his four-month-old son. Woo admitted in the Court of First Instance to trafficking in 1.3 kilograms of heroin. His family and friends were reduced to tears as they watched the father and son playing. The court heard that on September 27, Woo, a chef, was spotted carrying a black plastic bag by Customs officers in Tuen Mun. When he was searched, a block and a small packet of heroin were discovered. His keys were taken and his flat in Wing Fat Lane, Tuen Mun, searched by police and Customs officers, prosecutor Edward Brooks said. Blenders and tools for packing drugs were found with traces of heroin on them. After being cautioned, Woo confessed that the drugs were his, claiming some of the heroin was for his own consumption, Mr Brooks said. Mr Justice Thomas Gall said the case was 'a simple matter, a simple offence, but a serious crime'. The guards allowed the baby to be brought to his father after the judge had delivered his sentence and left the court. As the guards led Woo to the cells below the court, he waved to his wailing family.
