The alleged leader of a Southeast Baltimore Bloods gang was indicted by a federal grand jury on drugs and weapons charges, federal prosecutors announced.

Kevin Chambers, also known as “BK” and “Kaos,” is alleged to have led a gang called the Rollin’ 20’s Bloods that sold large quantities of crack cocaine and heroin along Fayette Street, around one of the city’s most persistently troubled areas, and in Patterson Park.

The indictment comes about two weeks after two men were shot within an hour in the nearby McElderry Park neighborhood, and two sources told The Sun at the time that the shooting was believed to stem from a dispute between the Rollin’ 20’s Bloods and a group called the Lueders Park Pirus.

"We are pulling out all the stops to accelerate federal violent crime and gang cases in an effort to head off additional shootings this summer and continue to build on the positive momentum of recent years," said U.S. Attorney Rod Rosenstein in an e-mail.

Court papers allege that Rollin’ 20’s members possessed and distributed firearms and committed acts of violence, including armed robberies and assaults, though it does not detail those incidents.

Chambers, 29, of the 1100 block of N. Milton Ave. faces a maximum sentence of life in prison for drug conspiracy charges and a maximum of 20 years for gun conspiracy charges.

He was indicted May 25 in Baltimore Circuit Court on several drug-related charges. He was convicted on handgun charges in 2007, receiving a suspended sentence and three years probation, and has prior drug convictions.
