This weekend, adult film star Brian Pumper was caught on camera, beating up a man at the Hollywood train station in Los Angeles.
A passerby spotted Brian squaring up against another man, a much smaller Caucasian guy. In the video, you see Brian move towards his opponent aggressively - then he starts swinging.
Brian's opponent immediately goes into a defensive crouch and eats all the punches that Brian throws at him.
Unfortunately the train pulled off, before we could see how the fight ended.
Here's the video:
Brian has not spoken publicly on what caused the fight.
