A police officer has been caught on camera tasering a 14 year-old girl – even though she appears to be surrendering.
The officer fired the high-voltage weapon at the teenager's groin, causing her to collapse in agony on the ground.
The shocking film came to light as part of a lawsuit being filed against the policeman, Jason Ammary.
Keshana Wilson, from Allentown, Philadelphia, was tasered outside Dieruff High school as she was walking with a group of friends in September.
Though 100 seconds is missing from the video, it captures the final encounter between the girl and the officer.
The policeman claims the Miss Wilson resisted arrest and elbowed him in the chin, but the lawsuit claims he grabbed her from behind without identifying himself and shoved her into the car.
In the film, the 14-year-old is seen walking towards the car before it abruptly cuts to her being slammed against the side of it by the officer. After a struggle, the officer steps back and fires his Taser at her groin.
According to the lawsuit, the police report claims Mr Ammary aimed his weapon lower because Miss Wilson was using her backpack to block the Taser.
But in the video Miss Wilson's upper body is clearly exposed – and she also appears to raise her arms about a second before he shoots at her.
She was taken to hospital to have probes removed before being arrested and charged with aggravated assault on the officer, simple assault, riot, resisting arrest, disorderly conduct, failure to disperse and walking on the highway.
The assault and riot charges were dismissed in juvenile court.
According to the local newspaper the Morning Call the lawsuit filed against officer Ammary and the city of Allentown claims that the girl did nothing to provoke the officer but that he grabbed her from behind and shoved her into the car while making insulting remarks.
But Allentown police say that Miss Wilson was cursing, inciting a crowd of students and resisting arrest - which included elbowing the officer in the chin.
