A man was arrested by Customs officers at Chek Lap Kok airport yesterday for allegedly trafficking 4kg of the designer drug 'ice' with an estimated street value of $1.2 million. Officers believe the consignment originated on the mainland and was destined for Malaysia. A 21-year-old Malaysian man is due to appear at Tsuen Wan Court today charged with trafficking in dangerous drugs. Officers from the Customs Airport Investigation Division intercepted a man who had been due to fly to the Malaysian city of Kota Kinabalu. The drugs were allegedly found in his baggage with two packets of ginseng - often used to throw off tracker dogs. The man said he was working in the valet parking business. Officers claimed he was a courier for a drug syndicate based in Malaysia, where demand for the stimulant is high. Officers also allege the man claimed he was paid M$5,000 (HK$10,270) to smuggle the ice to Malaysia. Yesterday's seizure was the first case of ice smuggling to be detected at the airport this year. Last year Customs officers detected seven cases, made 12 arrests and seized 21.3kg of the drug, worth $6 million. A senior Customs officer said: 'We are closely monitoring this trafficking trend.' On Friday, a Malaysian father of two who acted as a courier for an ice trafficker was jailed for 15 years. Madam Justice Clare-Marie Beeson sentenced Tan Lye Heng, 39, after he pleaded guilty in the Court of First Instance to one count of trafficking more than 1.78kg of ice and one count of using a false travel document. The court heard Customs officers were led to Tan after his companion was searched at Chek Lap Kok on April 19 last year and drugs were found. When they searched Tan they did not find any drugs, but a flight attendant said she had seen him visit the toilet, where officers found seven packets of ice.
