CHANTILLY, Va. (AP) — Federal agents fanned out across the United States in early morning raids Wednesday aimed at dismantling the upper echelon of the Jalisco New Generation Cartel, known as CJNG.

More than 650 people have been arrested, more than 15,000 kilos of meth has been seized and nearly $20 million has been taken by authorities.

For the U.S, combating Mexico’s fastest-growing and most violent gang is a top priority. Law enforcement officials believe the gang has drug distribution hubs in Los Angeles, New York, Chicago, Houston and Atlanta. And it’s believed to have a presence in 24 of Mexico’s 32 states.
