Katt Williams allegedly pulled a gun on a man outside the Comedy Store in West Hollywood.

Katt Williams wasn’t even on the bill—but according to police, he apparently put on a little show anyway.

Los Angeles County Sheriff’s deputies were called to the Comedy Store in West Hollywood in the early morning hours Wednesday after the comedian is said to have pulled a gun following a run-in with another man at the club.

“There was some kind of dispute between Katt Williams and someone else at the Comedy Store,” Sgt. Dave Valentine of the LASD told E! News, noting that the incident occurred at around 2 a.m. “The dispute carried on down the street at which point it is alleged that Katt pulled out a weapon and threatened the other guy.”

By the time deputies arrived, Williams was gone and the officers proceeded to take statements from witnesses and the alleged victim, Valentine said.

“The incident is currently under investigation and in the hands of the detectives,” he added. There was no official word yet on what prompted the dispute and we’re told that Williams had not yet been in touch with the LASD. No warrant had been issued for his arrest, either.

Meanwhile, an eyewitness told us that Williams had not been scheduled to perform at the Comedy Store last night, but that sometimes the 40-year-old entertainer comes in regularly and will sometimes do a previously unannounced set.

Per this source, earlier in the night the Scary Movie 5 star had gotten into an argument with a man who got kicked out of the club for filming on the premises. The man returned to the sidewalk after he was kicked out and shot video of Williams and his friends on the Comedy Store’s patio, which appeared to make Williams upset.

The club managers sent the man on his way down Sunset Boulevard, the witness added, noting that it wasn’t known if this man was also the alleged victim or not.

Williams’ name had been out of the police blotter for a while, but he’s no stranger to brushes with the law. In April 2013, he pleaded no contest to evading police after engaging Sacramento cops in a low-speed chase and was sentenced to community service and three years of informal probation.

I wish he would just stay out of trouble and just make us laugh!
