Two weeks ago, War Machine, the enigmatic Bellator fighter otherwise known as Jon Koppenhaver, was celebrating his recent promotion to Brazilian jiu-jitsu brown belt on Twitter, and calling out several hopeful future MMA opponents.

Now, he’s using the social media tool to proclaim his innocence — as he is sought by Las Vegas police in connection with an attack on his girlfriend, and another man.

As Dana Becker reported here at Caged Insider, War Machine is the primary suspect in a three person confrontation which took place at his Las Vegas home. The other two involved, a man and a woman, sustained injuries not thought to be life-threatening. One of the two is adult film actress Christy Mack.

The incident is the latest in a series of violent episodes in the fighter’s life, including a felony assault conviction in 2010. He has served several stints in prison, most recently in 2012.

War Machine was subsequently released by Bellator MMA, who describe themselves as having “a zero-tolerance” domestic violence policy.

Here is a list of the Tweets sent by War Machine since the incident:

Christy Mack has stated she will respond today:

War Machine remains at large, as Las Vegas police have been unable to locate him.

A UFC veteran, War Machine has accumulated a 14-5 record in MMA and most recently fought in October 2013.
