Police in Texas are investigating claims of excessive force after an officer was caught on camera throwing an intoxicated woman to the ground of a parking lot during an arrest. The officer, Ben Johnson, who has been on the force four years, was answering reports of a drunk woman inside Deluxe Nails at a strip mall in Red Rock on Tuesday. When he arrived, he contained 27-year-old Viviana Keith, who was walking toward her car, and began handcuffing her. Johnson claims the woman started resisting him, forcing him to pull a fast and forceful take-down, however video taken on his cash cam and by a person in a nearby shop appear to show a different story.

'When I look back at the tape, I can see her head bounce off the concrete because when he threw her down, she wasn't able to brace herself,' the man told KVUE. 'She was absolutely unconscious. 'There were a couple of other gentleman in the store with me and we were saying 'is she breathing?' 'Because at first we weren't seeing her stomach rise and fall.'
