Police in Germany have released without charge British boxer Dereck Chisora following a bloody brawl with rival UK fighter David Haye.

Chisora threatened to shoot David Haye after the two were involved in a brawl at the news conference following Chisora's WBC heavyweight title loss to Vitali Klitschko.

Chisora accused Haye of "glassing him", before saying at least four times that he would shoot the former WBA heavyweight champion.

He then added: "If David don't fight me, I am going to physically burn him."

Haye's manager, Adam Booth, also suffered cuts to his face in the melee.
