SIMI VALLEY (KTLA)-
A mixed martial-arts fighter from California who was sought in connection with the beating of his adult film star ex-girlfriend was arrested Friday in Simi Valley.
Jonathan “War Machine” Koppenhaver, 32, was taken into custody about 1:45 p.m. in Simi Valley by police at the request of the U.S. Marshals Service.
An arrest warrant had been issued for Koppenhaver stemming from an incident in Las Vegas last week, according to police.
Christy Mack, Koppenhaver’s ex-girlfriend, on Monday posted graphic photos on Twitter showing injuries she said were dealt to her by Koppenhaver. A friend who was with her was also assaulted, she said.
