Harrowing footage shows a nurse slamming a teenage mental health patient into a wall and attacking him with his crutches.
Hayden Vice, who was 15 and had a broken leg at the time of the vicious assault, was living in a psychiatric hospital in America when he was confronted by Isaac Doughty.
The horrific incident unfolded as Doughty, a mental health technician, met the teenager in the corridor and asked him to take a shower.
When he refused because a nurse had warned him not to get his leg cast wet, Doughty got angry.
Vice replied: "No, the hell I'm not - I'm going to do what the nurse told me to."
