Chief Keef Arrested On Trespassing Charges Minutes After Pleading Guilty To Speeding. Cheif Keef is leading the rap game in one category.. the number of arrests in one month.. The 17-year old, real name Keith Cozart aka Cheif Keef was arrested again today according to the Chicago Tribune. Keef had just pleaded guilty to speeding last month on the Edens Expressway in Northfield, Illinois. He was clocked going 110 mph in a 55 mph zone.. “You think you’re invincible, and you’re certainly not,” Cook County Circuit Court Judge Earl Hoffenberg told him in court this morning. “Violate (conditions of the plea agreement) and you’ll find out you’re not. I sure hope I don’t see you again, because if I do you better be ready to go to jail. If I were you, I wouldn’t take this deal if you can’t follow these conditions, I’m really not sympathetic to people who don’t listen to me.“ The judge fined the rapper $531, put him on probation for 18 months, ordered him perform 60 hours community service, and undergo random drug testing. He must also complete eight hours of traffic school. Minutes after leaving the courthouse, Keef was stopped by Chicago police and placed under arrest again. His attorney Leah Starkman said her client was picked up for misdemeanor trespassing. Starkman said police had taken Keef to the the Grand Crossing District station. This is Keef’s third arrest since May 20th.
