The 17-year-old appeared in Cook County juvenile court in Illinois earlier this week to face allegations he illegally fired a weapon during a video interview at a New York gun range last year, which went against the terms of probation on a 2011 firearms conviction.
The judge remanded him in custody and on Thursday he was sent to a juvenile detention center for 60 days. He will be given the right to appeal the ruling after 30 days behind bars.
The sentence means the hip-hop star will be forced to cancel his planned U.S. tour.
