A middle school teacher was caught on camera embarking on a bullying tirade against one of his students, and the victim's parents are now hoping the sickening video of the attack will lead to criminal charges.

John Rosi not only didn't try to stop the cruel act against the eighth-grader at the Kopachuck Middle School in Gig Harbor, Washington last February, he even gleefully joined in, reported the News Tribune.

During the 15-minute attack that was caught on many pupils' camera phones, a dozen classmates dragged the smaller boy around the room, holding him like a hammock, peeling off his socks, writing on his feet, stuffing a sock in his mouth, holding a pillow over his face and covering him with a chair.

Rosi can be seen smiling for the camera and encourages the bullies by poking the boy in the stomach and then pretends to sit on him, crassly pointing his butt toward the boy’s face and saying, “I’m feeling kind of gassy.”

After authorities were made aware of the incident last spring, the teacher, a 14-year veteran of the Peninsula School District, was suspended for 10 days and shifted out of Kopachuck classrooms, according to the terms of an agreement signed in April of this year.

He now works in a different school, but the boy's parents do not think the punishment fits the crime and they are demanding a criminal investigation.
