Three US cops have been suspended after horrifying footage shows them repeatedly using a taser on a boy, 18, while he was tied to a chair.

Jordan Elias Norris suffered more than 40 pairs of taser burns after being arrested and held in jail for nearly two weeks on drugs and weapons charges.

One of the officers is heard telling Norris that he was going to keep tasering him until he “ran out of batteries”

Every time they tased him Norris’s body would tense up from the electricity and the deputies would then accuse him of resisting so continued to fire the taser.

All three deputies in the video have now been placed on administrative leave while the incident is investigated.

Norris, now 19, has filed an excessive force lawsuit against the police department.
