SAN FRANCISCO (AP) A federal judge is sending a California man charged with operating a notorious online drug marketplace known as Silk Road to New York to face charges.

The order by U.S. Magistrate Judge Joseph Spero came Wednesday during a brief court hearing in San Francisco for Ross Ulbricht. Federal authorities in New York have charged the native Texan with three felonies related to the operation of the website.

Ulbricht's attorney, public defender Brandon LeBlanc, has denied the charges.

Silk Road gained widespread notoriety two years ago as a black market bazaar where visitors could buy and sell drugs using bitcoins, a form of online cash. A so-called hidden site, Silk Road used an online tool known as Tor to mask the location of its servers.
