A 19-year-old college student is suing UFC middleweight champion Michael Bisping for allegedly choking him during a gym altercation three months ago in California.

The plaintiff, Antonio Georgakopoulos, filed a lawsuit in Orange County on Monday, accusing Bisping of battery, assault, false imprisonment and intentional infliction of emotional distress.

TMZ first reported news of the lawsuit, a copy of which was obtained by ESPN.

According to the complaint, the alleged incident occurred July 31 at a 24 Hour Fitness.

The complaint states Bisping confronted Georgakopoulos for taking his weights and called him a "punk" and an "idiot." The complaint goes on to say that "at some point" Bisping extended his right arm to "squeeze [Georgakopoulos'] neck for two to three seconds."

Bisping allegedly released Georgakopoulos after another gym member intervened and yelled, "Let's take this outside!"

"It is completely inaccurate," Bisping said during a conference call on Thursday. "It is not factual. He filed papers. I haven't actually received any notification -- I haven't been served or anything -- but I've heard about this. No distraction there, mate. Honestly, I'm not losing any sleep over it whatsoever."

Anaheim Police Department public information officer Sgt. Daron Wyatt confirmed to ESPN that officers responded to the incident, but no arrest was made. Wyatt said Bisping already had left the area by the time officers arrived, but he has "fully cooperated with the investigation."

According to Wyatt, the city attorney's office already has reviewed the investigation and determined there was not enough evidence to support criminal charges.

Bisping's representatives did not immediately respond to requests for comment.

In addition to Bisping, Georgakopoulos has named the UFC and parent company WME-IMG, as well as 24 Hour Fitness, as defendants.

The complaint states Georgakopoulos suffered injuries to his throat and neck. He is seeking punitive damages "in an amount appropriate to punish the defendants and deter others from engaging in similar misconduct."

Bisping, 38, is scheduled to defend his title against Georges St-Pierre at UFC 217 on Nov. 4 in New York.
