(CNN) -- The family of an eight-year-old boy who committed suicide is suing Cincinnati Public Schools.
The lawsuit claims their son's school administrators failed to help protect him from aggressive and sometimes violent bullying.
Gabe Taye's parents say they could have prevented his suicide if they'd known about what this video shows in the bathroom at Carson Elementary.
You can see a student punch a boy in the stomach.
Gabe walks in and shakes the bully's hand, who thengrabs his arm and yanks him toward the wall.
He's knocked unconscious, but his parents were told he fainted.
This was two days before the third grader killed himself.
"If I’d known about this, you know I wouldn't, I would never send him to that school. He would have changed school. Go to another school. And this wouldn't have happen. This would've stop. It could have saved them,” says father Bini Taye.
"I trusted them with my son. I trusted them. They failed. They didn't protect him when I left him there with them,” says mother Cornelia Reynolds.
The suit says there were several incidents of bullying and aggressive behavior involving Gabe and other students, but often the parents weren't told.
Jennifer branch/attorney: "We allege in the complaint that the board of education, the superintendent, the principal, the assistant principal covered up the bullying that Gabe was a victim of,” says attorney Jennifer Branch.
The suit says two days after the bathroom incident there was another one.
Two boys took Gabe’s water bottle and tried to flush it down the toilet that night he killed himself.
