COOK COUNTY CRIMINAL COURTHOUSE — Michael Taylor Bennett, brother of Chance the Rapper and an up-and-coming entertainer in his own right, is charged with beating a drunk man at a college party after the man accidently stepped on his foot, prosecutors said.

With another guest pointing a cellphone camera at him, Bennett proceeded to beat the man, punching, kicking and stomping him, Antonietti said.

Kalmin, 21, jumped in, prosecutors said. They left the man bleeding from the head and ran from the party, prosecutors said.
