Businessman extradited from Cambodia to China suspected of running vast online criminal empire

Chen Zhi boasted of pulling in $30 million a day, prosecutors in the United States said — a suspected criminal mastermind and onetime internet cafe manager who authorities say presented himself as a legitimate businessman. On Thursday, Chen was in custody in China, at the center of what authorities at the Chinese Ministry of Public Security said was a “major achievement” in law enforcement cooperation between them and the Cambodian government. Chinese police marched Chen from a China Southern flight with a cloth cover on his head and his hands chained.
