The video, from a classroom camera, had been sealed eight years ago.
A description of the video can be found at MyFox/Boston and follows.
Andre is shown seated at a desk inside a classroom as a staff member asks him several times to remove his coat. He stays still, apparently not responding or removing his coat, until he is given a shock.
He screams and falls to the floor, yelling as he tries to hide under his desk. He was eventually restrained face-down, a helmet on his head, without breaks for food, water or the bathroom.
