A former agent of the U.S. Drug Enforcement Administration who was a key player during the government’s Silk Road investigation was sentenced to 78 months in prison for corruption.

Carl Force pleaded guilty on Monday to charges of extortion, money laundering and obstruction of charges, Reuters reported. He worked undercover for two years for an interagency team tasked with identifying the owner of Silk Road.

Force was the lead agent behind an authorized alias created to communicate with Silk Road creator Ross Ulbricht, but authorities said Force also created unauthorized personas to extort $250,000 from Ulbricht and offered to sell information about the information for $100,000. The man also admitted stealing 925 bitcoins worth approximately $100,000 and entering a $240,000 contract—without DEA approval—with 20th Century Fox Film Studios for a movie about the Silk Road probe.

U.S. District Judge Richard Seeborg said the scope of Force’s betrayal was “breathtaking,” according to the report.
