MMA Fighter Jonathan “War Machine” Koppenhaver Arrested

Koppenhaver tweeted earlier this week about being "cursed" and that police "never believe me."

MMA fighter Jonathan "War Machine" Koppenhaver was arrested at a Southern California hotel Friday a week after an alleged confrontation with his ex-girlfriend, adult film actress Christy Mack.

Koppenhaver was sought by law enforcement for one week after allegedly assaulting Mack in Las Vegas on Aug. 8, according to the Simi Valley Police Department and the US Marshals Service.

He was wanted by Las Vegas police on suspicion of battery by strangulation, domestic battery, assault with a deadly weapon, coercion with force, battery substantial bodily harm, and open and gross lewdness, officials said.

Mack claims Koppenhaver left her with 18 broken bones in her face, a fractured rib and a ruptured liver. She shared photographs of the attack with NBC News and on her Twitter account.

He was arrested about 1:45 p.m. at the Extended Stay America Hotel in the 2400 block of Stearns Street in Simi Valley, police said. Police found cash and pizza inside his room.

"Police came, they used a battering ram to batter down the door," hotel guest Mary Casamento said. "We heard some loud thuds and banging, it sounded like chairs or furniture."

According to the US Marshals Service, Koppenhaver had been hiding out at the hotel for a few days.

Mack took to Twitter about the alleged confrontation.

Koppenhaver tweeted earlier this week about being "cursed" and that police "never believe me." He also tweeted Mack, saying he "can't believe what happened."

A person who identified himself as a Koppenhaver family spokesperson told NBC4, "The family does not have anything to say."

Koppenhaverwas awaiting extradition to Las Vegas. He faces multiple battery and assault charges.
