17-year-old rapper Chief Keef, real name Keith Cozart, has been arrested in his hometown of Chicago for violating the terms of his probation. Cozart is currently serving 18-months probation for pointing a gun at a police officer in 2011. The Chicago Tribune reports that Keef was filmed holding a rifle at a New York gun range and the judge ruled it a violation.
In addition to pointing a gun at an officer, Keef has also been charged with manufacturing and distributing heroine, and is being investigated in the shooting death of another aspiring rapper.
Keef released his debut album on Interscope Records in 2012, after being discovered by Kanye West.
