A 21-year old Shelbyville man who was skateboarding in Rogers Park at 3 in the afternoon on Sunday got an unwelcomed surprise. The man told police that a black Chevy Impala pulled up at the park and hollered for him to come over. Thinking he may know the occupants of the car, he walked over. The victim tells police what happened next was anything but welcoming. Four subjects got out of the car and started beating him for absolutely no reason. The man recalled that after he fell to the ground they continued to punch and kick him. As far as getting a description of the assailants, all he could say was that they were four black males, one wearing an L.A. Lakers shirt. So far, an arrest has not been made.
