Shocking video - New video shows school security beating a student in a wheelchair

This is new video related to the incident I uploaded last week http://www.liveleak.com/view?i=6d3_1401475066 Oakland School District released new surveillance video showing a school security guard beating a special-needs sophomore on May 19. 17-year old Francisco Martinez was allegedly attacked by 23-year-old school resource Officer Marchell Mitchell along with being attacked in the hallway, Martinez says he was beaten and thrown to the ground in an elevator. The new video shows four school security guards surrounding Martinez. The student struggles as two men hold him down. Then, one can be seen pushing him over and kicking him in the head. The beating persists when they drag him onto the elevator, continuing to attacking him. The video released last week shows a guard in a white shirt pushing the wheelchair with Francisco Martinez down the hallway, but along the way you see the guard's right hand smack the student. Seconds later he hits him again and Martinez is thrown out of his wheelchair onto the floor. The district immediately fired Marchell Mitchel who they say had been hired as a substitute security officer in November and passed a background check. "Then responded in an extremely punching the student several times, throwing him several times," said Oakland Unified School District Spokesman Troy Flint. Mitchell was arrested by Oakland Police and district attorney has filed felony charges of corporal injury to a child.
