The FBI and Los Angeles Police Department on Thursday arrested at least 35 alleged gang members who for decades have controlled drug trafficking around a 1-square-mile area of southwest Los Angeles.

Hundreds of heavily armored LAPD officers and FBI agents carrying more than a dozen federal drug indictments raided locations in the Baldwin Village area, arresting suspected members of the Black P Stones gang.

Those arrested were taken to the L.A. Sports Arena, where dozens of officers massed for predawn raids. The raids were the latest example of the increasingly federal approach to L.A.'s most troubling gangs.

The arrests come at the conclusion of a more than a year of investigation and six years after a similar raid with federal and LAPD officers netted 28 members of the gang's leadership. All of the charges are related to drug offenses.

The Black P Stones have deep roots in a gritty section of low-slung apartment houses between La Brea Avenue and Crenshaw Boulevard south of Coliseum Street. Baldwin Village, for generations known as "the Jungle" for its rich assortment of tropical foliage, was the backdrop for portions of the crime film "Training Day."
