According to TMZ
Eyewitnesses tell TMZ … Katt was inside the club when a heckler started talking smack about the comedian’s height and race. We’re told Katt was not on stage … he was milling around. An eyewitness says he went crazy, threatening the heckler with a gun.
At that point someone called 911 — reporting a man with a gun at the Comedy Store — and 6 cop cars raced to the Sunset Strip. Deputies pointed shot guns and bean bag guns at the club as they prepared for a confrontation.
Turns out … Katt had already left.
So far no arrest warrant has been issued for Katt. Cops tell us they’re still investigating.
