The student holding the camera phone laughs maniacally as Nadin falls from the tree and attempts to escape by running through the Park Lane East apartment complex. They chase him down - then use his coat to hang his limp body on a 7-foot-high spiked fence post.
"The back of his head could have went into that spear-like top of the fence," Chitwood said. "He could have been impaled."
Outraged by the incident, Upper Darby police brass responded yesterday morning by sending officers to the Opportunity Center to arrest six of the alleged perpetrators, ages 13 to 17. They were hauled out in handcuffs and put in a police wagon. Police are searching for a seventh person they believe was involved.
"We've got to send a message to these kids, to these thugs," Chitwood said.
If students bully or threaten other kids, Chitwood said, "You're gonna take a hike in handcuffs and in a wagon."
Last night, Nadin and his parents, Eric and Rebecca Wright, saw the video for the first time when a Daily News reporter played it for them.
"Are you kidding me? Are you serious?" Rebecca Wright said, shaking her head in disbelief at what police are calling the most heinous case of bullying they've seen.
After about a minute, tears welled up in her eyes. "I can't watch it," she said. "I'm just speechless. What did he do to deserve it?"
Nadin, an aspiring Marine, said he didn't know what led his schoolmates to attack him.
"I was trying to escape and to get away from them," he said. "For the first two days, some parts of my body still hurt, but after that, I just got mad every time I thought about it."
Chitwood said the kids' decision to film the incident made it more disturbing, but not unusual, given the ease with which video can now be recorded and disseminated.
