MUNICH  - Britain's Dereck Chisora was arrested on Sunday by Munich police in the wake of his brawl with ex-champion David Haye at a post-fight press conference after Chisora lost a title fight to Vitali Klitschko.

German police detained both Chisora and his trainer Don Charles for questioning as they were preparing to board a plane back to the United Kingdom and later arrested the heavyweight boxer at Munich police headquarters. "Given the events of Saturday evening, a criminal investigation is required," a spokesman for Munich police told SID, an AFP subsidiary.

Chisora is suspected of grievous bodily harm and threatening behaviour, the spokesman added, and police also want to speak to Haye before he leaves Germany.

The British Boxing Board of Control has already indicated they will launch an investigation into events leading up to the ugly melee in Munich when Chisora was heard to repeatedly shout that he wanted to "shoot" Haye.
