It happened around 9:13 p.m. on June 19 in the basketball court area behind Chatham Park Elementary School located on the 400 block of Allston Road.
Disturbing video posted on social media showed six boys attacking a 15-year-old boy.
One suspect was arrested shortly after the attack. Police say the individual was wearing the teen's "Yeezy" slides that were stolen during the assault.
A current listing shows the shoes can cost up to around $300.
In the video, the victim screams to the attackers as they were after the shoes. He can be heard screaming, "Just take them, bro!"
Those attackers, though, continued to chase and punch the victim.
