Chisora and Haye must be punished - Wladimir Klitschko

Wladimir Klitschko says Dereck Chisora and David Haye "must be punished" after brawling at a news conference following Chisora's WBC heavyweight title loss to Wladimir's brother Vitali.

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

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

Wladimir Klitschko told BBC Radio 5 live 's Mike Costello he was "really surprised" by the incident and it was unacceptable for the sport.
