(AP) — A Nebraska man has been charged in connection with alleges sales of drugs, gun and counterfeit currency on the Silk Road website.

Federal prosecutors in Baltimore say 26-year-old Sheldon Kennedy of Lincoln was arrested Wednesday in Miami. He is charged in a complaint with conspiracy to traffic controlled substances and other offenses. The complaint was filed Jan. 31 and unsealed Thursday.

Authorities say Silk Road, which had nearly 1 million registered users by July, generated more than $1 billion in illicit business from January 2011 through September. The website used Bitcoin, the tough-to-track digital currency, before it was shut down.

According to court documents, undercover agents in Baltimore bought cocaine and a pistol from Kennedy on Silk Road, and he sold counterfeit currency to another person in Maryland.
