LAS VEGAS (AP) — A fugitive mixed martial arts fighter has been arrested in California, a week after police say he brutally assaulted his ex-girlfriend in Las Vegas.

U.S. Marshals announced Friday that they’ve captured the 32-year-old named “War Machine” in Simi Valley.  He was booked into jail while he awaits extradition to Nevada.

Officers say the fighter, whose birth name is Jonathan Koppenhaver, is the primary suspect in a dispute that left his ex-girlfriend and her friend with serious injuries.

Adult film actress Christy Mack says he knocked out her teeth, broke her bones and sheared off her hair in the attack which happened on August 8th.

The welterweight fighter has had previous run-ins with the law and missed two years of his career while he spent time in jail.
