China's 'own Walter White' produced designer drugs in secret labs that were exported worldwide

Police have arrested a university chemistry professor who allegedly sold "millions of US dollars" worth of psychoactive drugs over the internet to clients in the United States, Britain, Canada and Australia, state media reported yesterday.
The professor, surnamed Zhang, first learned about the popularity of such drugs while teaching as a visiting academic in Australia, Xinhua reported.
He then started a chemical company in 2005 but had staff manufacture "hundreds of kilograms" of methylone, commonly used as a substitute for MDMA, or ecstasy, the report said.
Between March and November last year, the business sold at least 193kg of the substance to the overseas customers, Xinhua said.
The report did not provide a precise monetary figure, only quoting police as saying that Zhang earned "millions of US dollars" from the sales.
Xinhua dubbed Zhang "China's real-life Walter White" in reference to the fictional high school chemistry teacher and methamphetamine kingpin in the US hit cable TV series Breaking Bad.
