Derek Chisora, a British heavyweight boxer, was invited by the police after his boxing brawl against former WBA champion David Haye during the post-fight news conference. He was questioned by Munich police regarding an assault that caused harm and threat to Haye.

Chisora together with his coach, Don Charles, were held by the Munich police on Sunday at 10:30 a.m. for questioning. Chisora was heard swearing to God to shoot Haye the night before the conference. He was heard shouting while claiming that Haye throw a glass on him.

Frank Warren, Chisora's promoted, described the brawl as ugly, horrible and disgraceful. He told Sky Sports News that the event was a shame for British boxing. He, however, said it was not Chisora who started the personal fight between the two of them.

Chisora underwent almost seven hours of questioning before he was released. He was permitted to go back to England for now, but still carrying charges of simple assault according to Gottfried Schlicht, police spokesman.

Charges against Chisora will probably be reduced after Haye went missing. Police searched for him at the hotel, but he is nowhere to be found.

Chisora mocked Haye after losing the WBA title to Klitschko's younger brother Wladimir last year. The situation became intense to the point where both were exchanging blows.

Haye's outrage led him into a fight with other members of Chisora's entourage. His coach, Adam Booth, ended up bleeding on his head.

The fight went extreme, which resulted to the destruction of camera equipment. Security came and cleared up the fight.

Vladimir Klitschko, who currently holds the WBO, WBA and IBF titles, was ashamed of the incident. He claimed he was disappointment for making the sport too personal.
