Chisora-Haye brawl explained

BBC Sport's boxing correspondent Mike Costello explains how the "disgraceful" brawl between Dereck Chisora and David Haye unfolded at the news conference following Chisora's WBC heavyweight title loss to Vitali Klitschko.

Chisora threatened to "shoot" Haye during the heated exchange and added, "if David don't fight me, I am going to physically burn him".

Adam Booth, Haye's trainer, who worked with the BBC at the fight, was left with blood streaming down a cut on the centre of his face.
