Xie Jing Feng alias Richard, 50, the drug mafia don from Canada caught red handed on Vadodara-Mumbai highway on Friday.According to Narcotics Control Bureau (NCB) officials, the arrest of the leader got them to bust the first-ever methamphetamine producing unit near Vadodara on Friday. The officials have also arrested two Malay citizens in the case.Ayush Mani Tiwari, zonal director of NCB, Ahmedabad, told TOI that methamphetamine is a very popular drug in South-East Asian countries, Japan and United States. "The drug comes under amphetamine-type stimulants (ATS) that contains methamphetamine, amphetamine and Ecstacy. In early 70s, the drug was banned but it resurfaced in a big way in late 90s and since then, the drug is very popular in party circuits," he said.Though there were no reported incidents of methamphetamine usage in India, NCB sleuths have time and again got tip-off of its production and despatch to consumer countries. NCB has conducted raids in the past in Hyderabad, Kolkata and Gurgaon in the last five years."In this case, Richard used to come frequently to India where he visited Mumbai and Vadodara. In special meetings, Malaysians were also present. In the initial questioning, we have come to know that they made drug substances from freely-available chemicals with an alternate formula. They then used human carriers to send it outside the Indian boundaries," said Tiwari.NCB officials said that as drugs have an international market and very less investment, many youths were lured in the business. "If one is given up to Rs 40,000 just to deliver a packet from one country to another, who would not be tempted? We had recently nabbed a Taiwan citizen from Delhi airport who was found in possession of contraband. We are working on the leads in this case," said an NCB official.
