Heavyweight boxer Dereck Chisora was released without charge on Sunday after an astonishing press conference brawl with bitter British rival David Haye, whom he threatened to shoot.
Chisora, who had been defeated by defending champion Vitali Klitschko in Saturday's WBC heavyweight title clash here, was detained by police, along with trainer Don Charles, at Munich airport as he was preparing to board a plane home.
The pair gave statements, but were released on Sunday evening and allowed to return to the United Kingdom, although the whereabouts of Haye are unknown.
“Munich-based detectives are investigating allegations of grievous bodily harm and threatening behaviour by Chisora,” said a spokesman for Munich police.
“They are also investigating Chisora's trainer and Haye for assault. Both Chisora and his coach were arrested at Munich airport and have given statements, they have also named legal representation.
“After consideration, prosecutors decided to release them. The whereabouts of David Haye are still unknown.”
Munich police searched Haye's hotel room on Sunday morning, but there was no sign of the former WBA heavyweight champion.
The British Boxing Board of Control has already indicated they would launch an investigation into events leading up to the embarrassing melee in Munich, when Chisora was heard shouting that he wanted to “shoot” and “burn” Haye.
Thomas Puetz, president of Germany's Professional Boxers (BdB) Federation, said he never wanted to see Chisora box in Germany again.
“We are considering a boxing ban for Chisora in Germany,” Puetz told German website spox.com.
