Chicago rapper Chief Keef was arrested twice in May - once for marijuana possession, the other for speeding. It's the latter charge that has landed him in jail.
Keef (nee Keith Cozart) paid a $531 fine for the speeding charge (he was caught going 110 mph on Edens Expressway in Northfield, Illinois on May 27). He was also placed on 18 months probation, and required to complete 60 hours of community service and take random drug tests. When he tested positive for marijuana, the judge sent the 18-year-old baller to Cook County Jail for 20 days.
On May 20, Keef was caught with weed in an Atlanta hotel room. That case has yet to be resolved.
