16-year-old girl is TASERED and dragged down stairs at school after teacher calls police over teen using her cellphone.

Distressing footage has emerged of two Chicago cops tasering a 16-year-old girl at her high school. Dnigma Howard claims she was wrestled to the floor and tasered while her father watched on helplessly following an argument with a teacher over using a cell phone in class at John Marshall Metropolitan High School, on Tuesday morning. Shocking surveillance footage shows the girl bundled to the floor and dragged down a flight of stairs by the two officers, who have since been reassigned to another school. According to a lawsuit filed against Chicago police, the officers then held her down by stepping on her chest, punching her and then shocked her with a stun gun. The teen has an individualized education program to help manage her behaviour, but her father said the protocol in place wasn't followed.' She wasn't really fighting back. She was defending herself. They were kicking her and stomping her and stuff. She tensed up. That's a natural reaction of anybody,' her father said. Attorney Andrew Stroth said the two officers in the video had 89 per cent more complaints of excessive force than other members in the CPD. He said Howard 'did not instigate or provoke any type of attack.' Previous footage recorded by the girl's father captured the ugly interaction. As the police officers were escorting her from the building a distressing dispute erupted and was captured on film by the teenager's father, Laurentio Howard. In the cell phone footage, Dnigma is seen on the floor as two officers stand over her. One of the officers, who is holding a yellow taser, can be seen with their leg on Dnigma's thigh and she tries to kick and hit at them while rolling around on the floor. The other officer, who has also not been named, grabs the teenager's arm. Dnigma then manages to sit up but the officer with the taser keeps a foot on her leg and the other controls her arm. When she reaches for the taser, the officer swings for her face and shocked students can be heard shouting in the clip. Chicago Police claimed that Dnigma bit and kicked the officers and that one of them fell down the stairs while trying to escort her from the building. However, Mr Howard alleged the officer tried to 'push' his daughter down the stairs so she 'grabbed the police officer by the vest' in defence. He said: 'I couldn't believe what was going on. I was thinking, 'If I jump in they're going to shoot me. And if I don't jump in, they're going to hurt my daughter really bad''.' Mr Howard blames the school for not following the behavioural protocol they had agreed, which includes letting his daughter talk to a counsellor, for the incident. Both of the officers and Dnigma were taken to the hospital and treated for minor injuries. A Chicago police spokesperson said: 'The officers are currently on medical leave and they will be reassigned to different duties within the District.' Dnigma was charged with two felony counts of aggravated battery to a peace officer and two misdemeanour counts of resisting and obstructing a peace officer.
