Upper Darby Township Police Superintendent Michael Chitwood says Monday's arrests at Upper Darby High School are related to an assault that happened Jan. 11 in an apartment complex courtyard.
Chitwood says the suspects, ages 13 to 17, kidnapped the victim on his way home from school, dragged him through the snow, stuffed him in a tree and hung him by his jacket from a 7-foot-high fence post.
According to police, the suspects used a cell phone to record the incident, CBSPhilly.com reports. In the mobile phone video the boy is screaming for his attackers to stop. Investigators say they snagged the recording before it made it to YouTube.
Chitwood says the student did not suffer serious physical injuries. Police have not yet determined a motive.
"They're lucky they didn't kill him. They're lucky they didn't impale his neck into the progs of the fencing," Chitwood said.
"When these bums and thugs intimadate their fellow students and make the streets unsafe, it's unconscionable, we're not going to tolerate it, and they're going out in handcuffs," Chitwood said.
