Even more from today's Dereck Chisora vs. Vitali Klitschko event, as at the post-fight press conference Chisora got into a brawl with David Haye. Chisora dropped a clear but hard fought decision to Klitschko, becoming only the fourth man to make it to the scorecards against the champion.

Much had been made in the build up of Chisora's statements that he "wouldn't back down" like Haye had when he fought Vitali's brother Wladimir. The tension between Chisora and Haye boiled over after the fight as described through these multiple tweets from SI's Chris Mannix's Twitter:

Wladimir Klitschko is yelling at both Chisora and David Haye at the press conference. This is awesome.

Bernd Boente to David Haye: "You're out. You can't talk yourself into this fight."

Chisora and Haye are now yelling at each other. Incredible

Chisora yelling "how's your toe" over and over. Now he's rushing Haye. they are brawling

Still brawling. Haye threw the first punch.,

Chisora: "I'm going to shoot you. I'm going to physically shoot David Haye."

Chisora claiming Haye hit him with a bottle. Vince McMahon couldn't make this shit up.

Wladimir is standing on a chair laughing. Gives me two thumbs up. He's loving this.

Chisora: "If David doesn't fight me, I'm going to find him on the street and kill him. I'll burn him."

Adam Booth is beeding from a cut on his skull. Chisora telling him, "look in my eyes, I'm going to kill your fighter."

I'm told that the police are waiting for Chisora outside. Don't know who called them, but they are here for them.

It's insanity of the highest degree and I'm curious what is going to come of this brawl, the police involvement and Chisora's multiple...I guess you have to call them death threats.

To be clear, Chisora is a bad guy and a bit of a loose cannon. He's assaulted a police officer in the past, picked up an assault charge for attacking his girlfriend, as well as possession of a weapon and has a history peppered with run-ins with the law. That's not to say that he's "actually" going to shoot Haye, but it may add some gravity to the statements and have driven the police intervention.

Wladimir enjoying two of his most hated rivals getting into it is pretty hilarious though.
