The accused included a 17-year-old boy who was charged as an adult with one count of robbery and one count of aggravated battery, the Chicago Tribune reported Wednesday.
A 15-year-old girl and five male teenagers were named in juvenile delinquency petitions on the same charges.
Police said one of the teens videotaped the attack showing the 17-year-old victim lying on the ground in an alley pleading for his assailants to stop punching and kicking him.
The attackers took shoes out of the victim's backpack. They also stole a wallet that contained $180 in cash.
Police said the attack did not appear to be racially motivated.
The victim was treated at a local hospital for a laceration to his lip, bruises and lacerations.
