A Hong Kong man is accused after the world's biggest seizure of the designer drug A case involving the world's biggest seizure of the designer drug Ice opened yesterday at a court in Guangzhou. The seizure of 12.36 tonnes of the methamphetamine in 1999 nearly equalled the global haul for the drug in 1998, the Guangzhou-based Information Times reported. A register confirmed the case was being held at Guangzhou Intermediary Court but officials at both the court and the prosecutor's office refused to comment on the proceedings. Ten suspects, one of them a Hong Kong citizen, are being tried for the production, transport and sale of the designer drug. It is alleged the gang made the drug at a pesticide factory at Yinchuan, capital of Ningxia Hui Autonomous Region, before transporting it from western China to Guangdong, where they were caught before they could sell it. The case was uncovered by chance when Yunnan police were investigating a cross-border heroin drug trafficking ring in 1999. Police tracked the gang transporting opiates to a warehouse in Guangzhou. When they raided it on November 4 they found 119.2kg of heroin and 11.08 tonnes of highly concentrated methamphetamine. After questioning the suspects, police raided an address in Puning, Guangdong, 14 days later. There they found another 1.28 tonnes of Ice, bringing the total seizure to 12.36 tonnes, enough to cover a basketball court when laid out in boxes. The police report states that after finding the drugs, they then found the Ice factory in Yinchuan where, it is alleged, the gang set up a drug production base at a pesticide factory in October 1998. Between January and October, 1999, the gang allegedly made up to 12.26 tonnes of Ice. They then transported the drug more than 2,000km from Yinchuan to Guangzhou and Puning. Police found the suspects had packed the drug-producing equipment on to eight trucks, seven of which had been sent on to the Pudong district in Shanghai, with the remaining one sent to Nanping in Fujian province. After officers failed to find drug manufacturing equipment, they issued a warrant for the arrest of Zhang Qisheng. But Zhang had used a false passport to fly to Thailand from Kunming in Yunnan province on November 11, 1999. Zhang was on the run for nearly a year but was caught by Thai police on October 24, 2000. They charged him with using a fake passport. After 20 months of legal wrangling he was sentenced to 18 months' jail. But having served his time on remand, he was surrendered to Chinese police in June last year and repatriated the next day. By January this year, the police had caught all 10 suspects, including a Hong Kong resident identified as Chong Shun-sing. On August 22, the Guangzhou prosecutor accepted the case. A verdict is expected as soon as today.
