(Providence, RI) -- Twenty-six people have been indicted in a series of federal investigations into firearm and drug-trafficking in the Providence area. The U.S. Justice Department said on Monday that federal, state and local law enforcement agents and officers assigned to a pair of task forces conducted dozens of undercover investigations targeting individuals illegally obtaining and-or trafficking firearms, and trafficking narcotics, over the last 18 months. The feds say more than two-dozen firearms, including three AK-47 and two AR-15 assault rifles, along with significant quantities of heroin, fentanyl, crack cocaine and methamphetamine, were seized in connection to the investigations. Many of the suspects are alleged members or associated with street gangs.
