A federal grand jury in Boise has indicted 21 people in a major methamphetamine distribution and firearms investigation focused on the "Aryan Knights" gang, which authorities say is active both in and outside of prison. "Methamphetamine trafficking is Idaho's most serious drug crime," said U.S. Attorney for Idaho Wendy Olson. "The involvement of known gang members and the presence of firearms pose significant danger to our communities."

The indictments come as a result of a joint federal, state and local law enforcement effort involving the FBI, the Drug Enforcement Administration, the Internal Revenue Service, the Treasure Valley Metro Violent Crime Task Force and more. Five of the defendants were arrested earlier today; 12 already were in custody and there are outstanding warrants for the remaining four. Most are from Boise; there also are two from Twin Falls, one from Pocatello, one from Ogden, Utah and one from California. You can read the full announcement here from the U.S. Attorney's office.
