According to the officers, they found money and pizza in the hotel room.

Koppenhaver, 32, was turned over to the police where they transported him to Ventura County Jail, but will finally be brought to Las Vegas, where the beating allegedly took place.

The police did not give a detailed account regarding who else were the victims of the War Machine's rage, but his ex-girlfriend, Christy Mack, shared on Twitter that she broke her nose and ribs.

The adult film star also posted picture of herself showing her injuries on the social media site and said that her liver was ruptured and her eyesight has diminished, she tweeted.

In an interview with Mack, she said she and a friend were at her Las Vegas home on Friday, when the UFC star arrived at around 2 a.m. and attacked her friend.

After Koppenhaver was done beating the friend, he turned his attention to her, Mack said.

"He made me undress and shower in front of him, then dragged me out and beat my face," she said.

Mack revealed that Koppenhaver used to beat her but not "this badly."

Meanwhile, Koppenhaver answered the speculations in his Twitter account, he said the police will never believe him and that the entire ordeal was "heartbreaking."

The MMA fighter also said that he knew the truth will come out one day.
