LONDON — Dereck Chisora could face sanctions from British boxing's governing body for brawling with David Haye following his loss to WBC champion Vitali Klitschko.
The British Boxing Board of Control said Monday it has opened an investigation into Chisora's conduct before, during and after Saturday's title bout in Munich.
Chisora slapped Klitschko at the weigh-in Friday and spat water in the face of his opponent's brother, Wladimir, before the fight. He then brawled with former WBA champion Haye at the post-fight news conference and was questioned at length by German police on Sunday.
The BBBC said 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 his 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.
Munich police want to question Haye but "understand that he's back in England," police spokesman Werner Kraus told The Associated Press on Monday.
Kraus said several legal obstacles need to be resolved before a warrant could be issued for Haye's arrest.
"The criminal police are still investigating. If they decide to take it further, they will have to present the case to the state prosecutor for review," Kraus said. "Eventually the state prosecutor could decide to ask, in this case the British police, for help.
"But ultimately only the state prosecutor can make that decision."
Haye could face charges of simple assault and grievous bodily harm.
"The assault charge would be for a punch, while the charge of grievous bodily harm arises when someone is hit with an object, say a bottle or a (camera) tripod," police spokesman Wolfgang Wenger said. "But the investigations are still ongoing. It may be that during the investigation these charges are dropped or reduced.
"We can not say what the outcome with be."
A conviction for assault carries a possible prison term of up to five years, while grievous bodily harm could lead to a 10-year sentence.
"Only the judge can decide that, not the police," Wenger said.
Wladimir Klitschko said Monday he was "shocked and deeply embarrassed" by Chisora and his team.
He said "these kinds of actions ... must be stopped, otherwise the sport of boxing is going to go down the hill fast."
