article: 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. Investigation: Police in Red Rock, Texas, are into this video to see if officer Ben Johnson used excessive force when taking down Viviana Keith, 27, who was arrested amid reports of drunken behavior and DUI . Excessive?: The dramatic video shows the moment Johnson slams Keith into the ground, knocking her out . Take-down: Johnson says that Keith was resisting him, so he threw her to the concrete of the parking lot . Out: The move immediately knocked Viviana Keith unconscious, as her daughter (left) watched on . Battered: Vivian Keith, seen here in her booking photo following the incident on Tuesday, has been charged with DWI with a child younger than 15 and interfering with pubic duties . Both videos show Johnson throwing Keith to the concrete ground of the parking lot. Her head can be seen hitting the hard surface in the video taken nearby, and she passes out on impact. The main who took the video, who wished to remain anonymous, said he believed it was an excessive use of force. '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.' Another witness, Viviana Garcia, said she thought the woman had died. Furthermore, the woman's daughter, who is six-years-old, also saw the incident unfold. 'It looked like she was dead,' Garcia told the network. 'The little girl was screaming, ''Mommy, mommy''.' Dash cam: A second roll of footage was captured inside Johnson's car showing Keith being arrested . Resisting?: Johnson claimed that Keith resisted him and that he was forced to take her down . Slam: This is the moment officer Ben Johnson throws Viviana Keith to the ground during the arrest Tuesday . Round Rock Police Chief Allen Banks said the calls his department received about Keith said she was being 'very combative, very argumentative and also very intoxicated'. Callers also said that Keith had left her daughter in the car. They said she was driving 'erratic' and 'carelessly' when she arrived. Others claimed to have spoken to the daughter, who said she was hungry. Internal investigation: Round Rock Police Chief Allen Banks says he has reviewed the footage and believes Johnson acted within his rights . After seeing the footage, Banks said he thinks the officer acted in the right way. 'The officer was very professional, was talking to her calm, he wasn't excited, he wasn't angry,' Banks told KVUE. 'It's unfortunate, the fact that this lady did what appears to hit her head and was knocked unconscious, but I'll tell you, the officer did what he was supposed to do in a situation like that.' Keith was arrested and charged with DWI with a child younger than 15 and interfering with pubic duties. She is being kept at Williamson County Jail for the time being.
