Seven teens were charged early Wednesday in connection with the brutal beating, captured on video and posted on YouTube, of a 17-year-old boy in an alley in Chicago's Bridgeport neighborhood.

The rest of the youths, including two 16-year-old boys, three 15-year-old boys and one 15-year-old girl, have all been cited on the same charges and turned over to the juvenile detention center, the Chicago Tribune reports. Due to their age, their identities have not been made public and all but one of them live in Chicago -- the other is from Arlington Heights.

The attack took place around 4 p.m. Sunday in an alley behind James Ward Elementary School, located at 28th and Princeton.

The YouTube video shows the 17-year-old victim, a Curie High School senior, being punched in the face and kicked repeatedly by a group of attackers while being taunted with racial slurs over the course of more than three minutes. His attackers also robbed the victim of $180 in cash, in addition to his sneakers.

The beating victim ran away, shoeless, was taken to Mercy Hospital and Medical Center and was released, according to the Tribune.

Authorities do not believe the beating was racially motivated.

Chicago Police Superintendent Garry McCarthy told CBS Chicago that the attack was not an isolated situation, though it appeared to be retaliation for an earlier incident where the victim, allegedly, participated in a separate attack where some 20 teens jumped on two others last fall.

"This is a dynamic that has been going on for a while," McCarthy told CBS.

Chicago Mayor Rahm Emanuel weighed in on the beating on Tuesday and said that it should serve as "a wake-up call to all of us," NBC Chicago reports.

"Those kids doing that to another child is wrong. It is not tolerable and it does not represent what this city's values are and the good people of this city," Emanuel continued.

Area resident Carl Segvich commented to ABC Chicago that he was "outraged" by the attack.

"We have war in our cities right now, and if they would have had a gun, they would have probably shot the poor kid," Segvich told ABC.
