The Tulsa World reports the arrests were made Tuesday after federal authorities unsealed a 73-count indictment against 29 people in connection with an investigation dubbed Operation Smack Dragon. Officials say five defendants remain at large in Mexico or elsewhere.
Officials say law enforcement agencies executed search warrants during the arrests and reportedly seized 3 kilograms (6.6 pounds) of heroin, $150,000 in drug proceeds, two firearms and four vehicles.
Assistant U.S. Attorney Joel-Lyn McCormick says the investigation began in 2017 after investigators learned about the drug trafficking ring tied to the New Generation Cartel in Mexico.
