Jonathan "War Machine" Koppenhaver was arrested in Simi Valley, Calif. today, according to NBC News.
The MMA fighter has been accused of beating his ex-girlfriend, adult entertainer Christy Mack. An arrest warrant was issued for the 32-year-old mixed martial artist earlier this week stemming from an incident in Las Vegas, charging him with several counts of battery, assault with a deadly weapon and other crimes, police said, per The Los Angeles Times
Officials took Koppenhaver into custody around 1:45 p.m. on Friday, at the request of the U.S. Marshals Service.
Police said he was found at a Simi Valley hotel, where there was a "a small quantity of cash and some pizza" in the room before he was transported to the Ventura County Jail.
Earlier this week, Mack took to Twitter to share a series of extremely graphic photos of her injuries, which, she claimed she sustained as a result of a brutal beating by her ex BF.
She also released a lengthy statement in regards to the Las Vegas incident, alleging Koppenhaver arrived unannounced at her home in Sin City before he proceeded to assault Mack as well as her unarmed companion.
"Without a single word spoken, he began beating my friend; once he was finished, he sent my friend away and turned his attention to me. He made me undress and shower in front of him, then dragged me out and beat my face," she said, adding that her injuries include 18 broken bones around her eyes as well as a broken nose and missing teeth.
However, after she began making headlines for her allegations, War Machine took to Twitter to defend himself and even claimed that he was planning to propose to Mack (she claims the two split in May).
"I'm not a bad guy, I went to surprise my gf, help her set up her show and to give her an engagement ring and ended up fighting for my life," he wrote on Sunday. "The cops will never give me fair play, never believe me. Still deciding what to do but at the end of the day it's all just heart breaking."
"I only wish that man hadn't been there and that Christy & I would be happily engaged. I don't know y I'm so cursed," he continued. "One day truth will come out."
A fundraising page has been set up to aid with Mack's medical expenses. To date, the campaign has raised over $66,000.
