Melvin Guillard is in serious trouble with the law in Colorado.

The mixed martial arts veteran is facing charges of felony assault and misdemeanor domestic violence in Jefferson County, MMA Fighting confirmed Thursday after an initial report by TMZ.

Guillard was arrested April 23 by officers from the Lakewood Police Department. Guillard’s girlfriend told officers that, during an argument, Guillard put his hands around her neck and strangled her, because he didn’t want her to be too loud and wake others in the home, per an affidavit obtained by MMA Fighting via the Jefferson County District Attorney’s office.

The alleged victim said while he was choking her, she was “scared he might kill” her. She told officers that she slapped Guillard in the face to get him to stop strangling her. The two began arguing again, the alleged victim said, and when the volume raised Guillard grabbed her around the neck with one arm, put it under her chin and cut off her breathing. She said he began shaking her from side to side while strangling her.

Per the affidavit, when officers made contact with the alleged victim, they noticed her left eye was bruised and swollen. She told officers that the argument was about when Guillard would leave his wife to be with her.

Guillard told officers that he asked the alleged victim to quiet down while they were arguing to not wake anyone else up. When she didn’t, he said she would have to leave. Guillard told officers that’s when the alleged victim slapped him in the face. Guillard said he then grabbed her by the neck and lifted her to her feet. He told cops that she said, “What are you gonna do? Hit me?” To which Guillard said he replied, “no.” He said there was no further physical contact after that.

Guillard, 35, was in court Sept. 10 for the domestic violence case when he was arrested for another incident — an alleged assault at a Denver bar Sept. 3, Denver Police Department spokesperson Jay Casillas confirmed with MMA Fighting.

TMZ was first to report that situation, including the publishing of a surveillance video that appears to show Guillard knocking someone out with a right hand.

According to online records, Guillard is being held on $10,000 cash bond for four charges stemming from the bar incident: three second-degree assault and one third-degree assault. He remains in custody in Jefferson County as of Thursday afternoon, per records. Second-degree assault is a felony in Colorado.

On the domestic violence charges, Guillard is due back in court Oct. 10 for a pre-trial conference.

Guillard, who holds a 32–21–2 (3 NC) record in MMA, just fought at Rizin 11 in July, falling to Takanori Gomi by first-round knockout. Guillard, a New Orleans native, has not won a fight since 2014, a string of nine winless bouts.

The lightweight and welterweight fighter was in the UFC from 2005, when he was on The Ultimate Fighter 2, until 2014. After being let go by the UFC, Guillard, known for his exciting fighting style, competed for World Series of Fighting and Bellator.
