Tse Chi Lop is the criminal mastermind behind the largest drug trafficking operation in history. Investigators reveal how he stayed under the radar for more than a decade.

Dubbed Asia's 'El Chapo,' Tse is alleged to have built the largest drug trafficking operation in history, that stretched from drug factories in the Golden Triangle of Southeast Asia to involve the Italian mafia, Yakuza in Japan and motorcycle gangs in the U.S. His capture, as he attempted to fly from Taiwan to Canada via Amsterdam, required the cooperation of more than twenty government agencies and was coordinated by the Australian Federal Police.
