Former UFC fighter Jon “War Machine” Koppenhaver arrested on battery charges in Las Vegas

Former UFC welterweight Jon Koppenhaver, now legally known as War Machine, has found himself in more legal trouble.

A source speaking on the condition of anonymity informed FiveOuncesOfPain.com early Monday morning that Koppenhaver had been arrested by Las Vegas Metro Police over the weekend.

Jay Rivera, a representative with the Public Information Office of the Metro Police Department, confirmed that Jonathan Paul Koppenhaver was arrested Saturday, February 8 at approximately 4 a.m. local time. According to Rivera, a citizen’s arrest was made of Koppenhaver on charges of misdemeanor battery.

Koppenhaver, a cast member on the sixth season of The Ultimate Fighter, had received three years probation and was ordered to pay $2,300 in restitution last February for his felony assault of Darren Zutkow outside a California gym in September of 2007.

Known for his often-erratic messages left via his official MySpace account, Koppenhaver recently was released by the Bellator Fighting Championships following a blog in which he endorsed a potential assassination of United States President Barack Obama.

Koppenhaver, 6-2, had been signed by Bellator as a participant in its upcoming eight-man welterweight tournament, which is scheduled to commence in April.

The current Las Vegas resident had also been released from his contract with the UFC after reportedly turning down a fight against Brandon Wolff and then also publicly speculating about the death of former UFC middleweight champion Evan Tanner.
