LONDON (AP) -- Dereck Chisora could face sanctions from British boxing's governing body for his behavior before, during and after his loss to WBC champion Vitali Klitschko.
The British Boxing Board of Control said Monday it has opened an investigation into Chisora's conduct in connection to Saturday's bout in Munich. Chisora slapped Klitschko at the weigh-in and spat water in the face of his opponent's brother, Wladimir, before the fight. He then brawled with former WBA champion David Haye at the post-fight news conference, leading to him being questioned at length by German police on Sunday.
The BBBC said Monday that it is investigating Chisora on a misconduct charge.
The body is looking into his behavior "prior, during and after his contest" against Klitschko, BBBC General Secretary Robert Smith said in a statement. "A further statement will be issued once the stewards have decided on what action will be taken."
Chisora taunted fellow Londoner Haye about losing the WBA belt to Wladimir Klitchko in July, leading to a heated exchange before the pair came to blows. Haye also fought with members of Chisora's entourage, and his coach, Adam Booth, was bleeding from a cut on his head.
Haye, though, looks likely to escape sanction by the BBBC because he officially retired after his defeat to Wladimir Klitchko.
"Mr. Haye is not a licensed boxer with the British Boxing Board of Control and therefore no longer under the jurisdiction of the British Boxing Board of Control," Smith said.
Chisora faces a charge of simple assault in Germany but was released Sunday after nearly seven hours of questioning by police. His coach, Don Charles, also faces a charge of assault for his involvement in the melee.
The pair have returned to England.
Chisora and Charles were detained at the Munich airport at 10:30 a.m. Sunday and taken for questioning to Munich police headquarters. Chisora was initially held on suspicion of assault, causing grievous bodily harm and of making a threat. Chisora was heard vowing to shoot Haye.
More serious charges were reduced when police were unable to find Haye despite searching for the boxer at his hotel.
Wladimir Klitschko said Monday he was "shocked and deeply embarrassed" by Chisora and his team.
Klitschko says "these kinds of actions ... must be stopped, otherwise the sport of boxing is going to go down the hill fast."
