The Chicago Sun-Times reports that Chief Keef has been taken into custody after a judge ruled he violated his probation. It was recently announced that the date of his probation hearing was moved up to today. He is expected to appear in court again this coming Thursday for a sentencing hearing.

Keef, whose real name is Keith Cozart, appeared in court because prosecutors argued that he violated his probation during an interview with Pitchfork at a New York gun range last year. The Chicago upstart was placed on probation following a sentence of home confinement, which stemmed from gun charges in late 2011.

Keef's fans have taken to Twitter to express their feelings on the news. In fact, at the time of this posting, #FREESOSA is the second most popular hashtag in the U.S.
