More than a hundred suspects have been charged in the Bronx in what is believed to be the largest gang takedown in New York City history, authorities said Wednesday.

Manhattan U.S. Attorney Preet Bharara, Police Commissioner Bill Bratton and other law enforcement officials announced the charges against 120 alleged members and associates of two rival gangs.

The early morning raid involved hundreds of law enforcement officers from the NYPD and federal agencies, some using helicopters and armored vehicles to round up the suspects.

Officials said the alleged gangs are the Big Money Bosses, or BMB, and the 2Fly YGz, or 2Fly. Bharara said they "allegedly wreaked havoc on the streets of the Northern Bronx for years by committing countless acts of violence against rival gang members and innocents alike."
