CHICAGO – Keith Cozart, better known as Chicago rapper Chief Keef, has been released from juvenile detention after serving 60 days for violating probation on a gun conviction.

Cozart left Cook County Juvenile Court after a brief hearing Thursday. Officials say there are no court restrictions on his activities.

The 17-year-old was sentenced last year to 18 months’ probation after his conviction on aggravated unlawful use of a weapon charges for pointing a gun at police officers.

In January, Cook County Juvenile Court Judge Carl Anthony Walker ordered Cozart’s arrest for a promotional video that showed the teen firing a semi-automatic rifle at a New York gun range.

Chief Keef’s first album, “Finally Rich,” was released last year to mixed reviews.
