OWASSO, Okla., , Dhu-AlHijjah 22, 1436, October 06, 2015, SPA -- An Oklahoma police officer turned himself in Monday for allegedly striking a motorist with the butt end of a shotgun following a high-speed chase in June, authorities said, according to UPI. Lt. Michael Dwain Denton surrendered Monday to face charges of assault and battery with a deadly weapon and reckless conduct with a firearm, stemming from the arrest of Cody Mathews on June 14, Tulsa World reported. Denton's surrender comes after the Council on Law Enforcement Education and Training concluded that such use of a shotgun on a suspect is not consistent with its teachings. After his court appearance, Denton was jailed and released on a $5,000 bond. According to court documents, Denton struck Mathews with the butt of the shotgun as he sat in the front seat of his vehicle following the pursuit. The gun also struck officer Cheyenne Lee as she was attempting to handcuff Mathews inside the vehicle. The court documents also say Denton, 49, continued to hit Mathews with the shotgun even after he was removed from his truck. In its investigation, the Oklahoma State Bureau of Investigation asked law enforcement training experts whether hitting a subject with the butt of a gun is an accepted method of de-escalating a terse situation. Both said the tactic is not taught to police officers and constitutes deadly force -- in a scenario that they believe did not call for such a police response. Mathews dropped a knife he held to his throat after the chase, according to video evidence, officials said. Two other police officers at the scene told investigators Denton should also have seen that Mathews was no longer holding the knife prior to striking him with the shotgun. Denton could ultimately be fired for the incident, depending on the conclusions of investigators. He was previously fired in 2011 stemming from another reported incident that officials said violated the agency's use-of-force policy. However, an arbitrator later reinstated Denton to the police force and the city of Owasso ultimately paid him more than $365,000 stemming from the firing. Denton was suspended with pay in June following the incident. --SPA 03:53 LOCAL TIME 00:53 GMT www.spa.gov.sa/w
