Authorities say Alton Hayes III was one of two people who attacked a man walking in the 600-block of North Kenilworth Avenue just before 1 a.m. Tuesday.
Hayes reportedly picked up a large tree branch, pointed it at the man and made a racially charged comment during the robbery.
Hayes and a 15-year-old boy were arrested a short time later. He is being held on $80,000 bond and is due in court Friday.
