Businessman Zhenli Ye Gon, accused of producing and trafficking methamphetamine, was extradited to Mexico Oct. 18. Placed by US Marshals on a flight from Virginia to Mexico City, he was upon his arrival immediately taken to the country's top-security lock-up, the notorious Altiplano Prison. The turn-over comes after he lost a nine-year legal battle against extradition from the US, BBC reports. Zhenli Ye Gon fled to the United States in 2007 after Mexican police seized $205 million in cash from his Mexico City villa. As South China Morning Post notes, this was hailed as the biggest cash haul in the history of global drug enforcement. Authorities say he was importing vast quantities of precursor chemicals for meth production. Ye Gon, who has dual Chinese and Mexican citizenship, denies the charges, maintaining that his company, Unimed Pharm Chem Mexico, was producing legal prescription drugs.
