Rapper Chief Keef arrested at hotel near Atlanta Police in suburban Atlanta say rapper Chief Keef, whose name is Keith Cozart, has been arrested and charged with disorderly conduct. Dunwoody, Ga., police spokesman Timothy Fecht says officers arrested Cozart after responding to a call about illegal drug activity at the Le MDeridien hotel just north of Atlanta on Monday afternoon. Fecht says officers saw smoke and smelled marijuana wafting from a room. It wasn't immediately clear what Cozart was doing in Georgia. Representatives at his booking agency said they didn't have contact info for an attorney for the 17-year-old Chicago native and didn't know much about the incident. The rapper addressed the arrest on Twitter, writing, "Jus Got Out Of Dekalb County jail In Atlanta Mad As [expletive]." He also shared a photo of his mugshot on Instagram. Cozart was arrested in January and spent about two months in juvenile detention for violating probation on a weapons conviction. He had received probation for pointing a gun at police in 2012.
