WASHINGTON- A Pakistani drug dealer, who operated through internet, has been sentenced to 15 years in jail by a US court on the charges of drug trafficking and money laundering. Shiraz Malik was arrested at the Prague International Airport in September 2011, and was extradited from the Czech Republic to the US in June 2012. Malik took orders from customers via internet and coordinated with people in Pakistan to fill the orders, the Justice Department said. Malik sold large quantities of ephedrine to customers in Mexico, the country of origin for most of the methamphetamine sold in the US, the Justice Department said. The US Attorney Benjamin Wagner said the defendant supplied addictive drugs, including oxycontin and heroin, to other drug traffickers in America and around the world, and supplied materials needed to make methamphetamine to clandestine producers in Mexico and Africa.
