The only person who threw a punch on Saturday night at Munich's Olympic Hall and isn't facing potential sporting and criminal ramifications is the defending champ, Vitali Klitshcko, who was able to contain his swinging fists to the ring in his victorious fight against Britain's Dereck Chisora.

Chisora, on the other hand, as well as retired British boxer David Haye, are in hot water following a brawl that broke out between the two during the press conference after the fight.

Police in Munich want to question Haye - nicknamed "the Hayemaker" - about the fight, police spokesperson Wolfgang Wenger said.

"There are of course investigations centred on him and the prosecutor will decide here how to get hold of him, whether this will happen in England or here," he said. "The judiciary must decide how to proceed."

State prosecutors in Munich must decide whether or not to pursue charges of simple assault and grievous bodily harm, which carry maximum penalties of five and ten years in prison, respectively.

Haye returned to England after the fight before police had a chance to track him down. Chisora was taken into custody by police at the Munich airport as he waited for his flight home. He was questioned and released.

Chisora faces ban

In a statement released Monday, Haye said he left Germany because of death threats made by Chisora during the press conference scuffle. Recordings of the fracas picked up Chisora repeatedly saying he would "shoot" Haye. Although Haye retired from boxing, he was working as a guest commentator for British broadcasters at the fight in Munich.

He has been considering a return to the ring to take on Klitschko, a scenario that Klitschko's manager, Bernd Bönte, has ruled out. Haye lost a fight against Klitschko's younger brother, Vladimir Klitschko, last year.

Chisora also commented on the incident on Monday, although he said he could not go into detail because the British Boxing Board of Control (BBBC) was still looking into the matter.

"I have a duty as a professional boxer to conduct myself properly at all times, especially with boxing being a sport of controlled aggression," he said. "I have let lots of people down on Saturday night, including myself, and for that I am truly sorry."

Chisora has been summoned to appear before the BBBC on Wednesday. The board has the authority to fine him, revoke his license, or ban him from the sport completely. German prosecutors could also still pursue criminal charges against him.

Since Haye is not an active boxer, he cannot have his license revoked by the BBBC, but the board could prevent him from getting a license should he decide to pursue a comeback.
