Chief Keef, whose real name is Keith Cozart, 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.
Earlier this week, Cook County Juvenile Court Judge Carl Anthony Walker ordered Cozart's arrest for a promotional video of the 17-year-old firing a semiautomatic rifle at a New York gun range.
The Chicago Sun-Times reports Cozart cried as he pleaded with Walker not to sentence him to detention. However, the judge said he wouldn't tolerate Cozart's "blatant violations of the court's order."
Chief Keef's first album, "Finally Rich," was released last year to mixed reviews.
