"War Machine," formerly known as Jon Koppenhaver, was apprehended by U.S. Marshals earlier today (Aug. 15, 2014) in Simi Valley, California, after a week-long manhunt which began shortly after the mixed martial arts (MMA) fighter was accused of assaulting ex-girlfriend Christy Mack in her Las Vegas home.

The incident took place immediately after the former Ultimate Fighting Championship (UFC) welterweight allegedly beat up a man who was quietly sleeping in Mack's home. All a part of a surprise marriage proposal gone wrong, according to Koppenhaver.

Nevertheless, the beatdown prompted law enforcement officials -- when they finally got around to it -- to issue seven warrants for his arrest (see a copy of the criminal complaint here), and he was also cut by Bellator immediately following the incident.

Arrest details straight from Nixle:

Further investigation revealed he was staying at the Extended Stay America Hotel located in Simi Valley. Simi Valley Officers alongside United States Marshals pinpointed his exact room and arrested him without incident. Inside the [hotel] room was a small quantity of cash and some pizza. The United States Marshal's Service turned Mr. Koppenhaver over to the Simi Valley Police Department for booking on his warrant from Nevada. He was transported to the Ventura County Jail.

Fortunately, no one else got hurt.

The much-publicized assault also caught the eye of Duane Chapman, better known to reality television show junkies as "Dog The Bounty Hunter," who warned the fugitive to turn himself in or risk losing his life in what was expected to be an inevitable confrontation.

Better luck next time, Mr. Dog.

Though he continues to maintain his innocence throughout the ordeal, War Machine will now have to plead his case to a judge and jury. But if his past run-ins with Johnny Law and these disturbing images carry any weight inside the court room, the future doesn't look so bright for the pro fighter.
