TAMPA, Fla. - Federal officials say a southwest Florida man has pleaded guilty to importing drugs through an underground website that accepted the digital currency bitcoin.

The U.S. Attorney's Office in Tampa said Tuesday that 34-year-old Angel Quinones imported at least 9,193 grams of MDMA, also known as Ecstasy, from an online Dutch supplier between 2012 and 2013, with the intention of selling it in the U.S.

Earlier this month, the supplier, 23-year-old Cornelis Jan Slomp, pleaded guilty in Illinois federal court in a deal with prosecutors. Slomp is accused of shipping 566,000 ecstasy pills, kilos-worth of cocaine and other drugs through the U.S. mail, making more than $3 million in bitcoins.

Slomp, a college graduate and former software engineer, was arrested in Miami after arriving on a plane from Europe.
