US law enforcement agencies have raided and closed down the notorious anonymous online marketplace known as the Silk Road and arrested its alleged owner. The site traded in illegal drugs like heroin and cocaine, sold illegal weapons, hacking tools and tutorials and also offered hit men for hire. The FBI has arrested William Ulbricht, 29, in San Francisco as the proprietor of the Silk Road, saying he operated under the pseudonym Dread Pirate Roberts. The FBI says the site was responsible for up to $1.3 billion in sales in anonymous Bitcoin currency and received more than $80 million in commissions. Federal prosecutors in New York charged Ulbricht with one count each of narcotics trafficking conspiracy, computer hacking conspiracy and money laundering conspiracy, the filing said. "Silk Road has emerged as the most sophisticated and extensive criminal marketplace on the internet today," FBI agent Christopher Tarbell said in the criminal complaint. The site was used by "several thousand drug dealers" to sell "hundreds of kilograms of illegal drugs," he said. The site, which has operated since early 2011, also offered tutorials on hacking ATMs, contact lists for black market connections and counterfeiters, and guns and hit men for sale, according to the charges. The internet's black market Drug dealers shed light on the growing online black market which is helping more and more Australians buy weapons and Drugs. Read the full report by the ABC's Conor Duffy. Ulbricht, who holds an advanced degree in chemical engineering, appeared in federal court on Wednesday and a bail hearing was set for Friday. According to the complaint, Ulbricht, who shortened his alias from Dread Pirate Roberts to DPR when posting on Silk Road's forums, operated the site from San Francisco. At times, he used computers at internet cafes to access the servers running the website, which employed several technological tools to mask the location of its servers and the identities of its administrators and users. The complaint described other aspects of Ulbricht's online presence: In a Google+ profile, he described himself as a fan of libertarian economic philosophy and posted videos from the Ludwig von Mises Institute, an Auburn, Alabama-based economics institute. Reached by phone in Austin, Texas, Ulbricht's parents said they had not known what their son was doing in San Francisco. "He is a really stellar, good person and very idealistic," said Ulbricht's mother, Lyn Lacava. "I know he never meant to hurt anyone." Ulbricht's father Kirk confirmed his son had received a master's in material sciences from Pennsylvania State University. His thesis was titled Growth of EuO Thin Films by Molecular Beam Epitaxy. "He did amazing research on crystals and exotic materials they hoped would have some use for humans," Mr Ulbricht said. "But it was very theoretical stuff." Claims of attempted hit on fellow Silk Road user The complaint against Ulbricht describes a darker side. During one correspondence with a Silk Road user, Ulbricht tried to call out a hit on another user with whom he had a dispute. That user, known online as FriendlyChemist, was threatening to expose the identities of thousands of Silk Road users unless Ulbricht sent him money. "I wouldn't mind if he was executed," Ulbricht wrote, offering personal details about his foe, including the fact that he was a married father of three, and the names of the city and province where he lived. In a later post, Ulbricht wrote: "He is threatening to expose the identities of thousands of my clients." "This kind of behaviour is unforgivable to me. Especially here on Silk Road, anonymity is sacrosanct." The raid on Wednesday (local time) is not the first time the US government has made arrests related to Silk Road. Earlier this year, authorities in South Carolina arrested Eric Daniel Hughes, known on Silk Road as Casey Jones, and charged him in state court with drug possession. The Drug Enforcement Agency seized units of Bitcoin, which Hughes allegedly used to purchase drugs from the online market. Bitcoin, which has been around since 2008, first came under scrutiny by law enforcement officials in mid-2011 after media reports surfaced linking the digital currency to Silk Road.
