They are reporting that his wife Jenna Jameson had "visible injuries" when the cops arrived at the Huntington Beach Bad Boy's house in California.
Ortiz was recently a coach on "The Ultimate Fighter" reality series on Spike TV. He was supposed to fight Chuck Liddell in the season finale. But was replaced by light heavyweight Rich Franklin because of personal issues with his family.
According to TMZ, a 911 call was received today at 9:53 a.m. Ortiz was arrested on domestic violence charges afterward.
Bloodyelbow.com has a video of Ortiz being led out of his house by the police and a video of his girlfriend Jenna very upset.
