An Arkansas cop has been fired after he was caught on video brutalizing a handcuffed man in the backseat of a patrol vehicle, punching the detainee in the face, smashing his elbow into his temple, and slamming the car door on his head after he appears to pass out.

On Friday, the Jonesboro Police Department released footage of the horrifying Aug. 8 incident, in which Officer Joseph Tucker Harris can be seen walking back to the car, flinging open the door, and grinding a metal baton into Billy Lee Coram’s sternum until he comes to, shrieking in pain. Harris then slams the door on Coram’s head again as the 42-year-old, wearing a hospital gown, can be seen writhing in agony. Coram had earlier tried to strangle himself with his seatbelt, the video shows.
