Four violent criminal organizations involved in drug trafficking in southwest Baltimore have been dismantled, Maryland law enforcement announced Monday.

Almost 40 people between the ages of 16-60 have been criminally charged thus far, and confiscations included 15 stolen vehicles, nearly 70 guns, and large amounts of narcotics and money. The crime bust was a collaborative effort of over a dozen local, state, and federal law enforcement agencies that officials called “Operation Tornado Alley.”
