Over and over, prosecutors have tried to put Chicago rapper Chief Keef behind bars for allegedly violating his probation.

Yesterday, the 17-year-old musician managed to stay out of jail again.

Chief Keef had to appear before a judge after it was alleged that he had moved without telling his parole officer. But the judge found "no credible evidence" of his being in Northbrook, as sources alleged.
