“He still faces a charge of simple assault but he is allowed to return to England for now,” police spokesman Gottfried Schlicht said.
Chisora and fellow Londoner Haye came to blows after Chisora’s defeat by unanimous decision to Vitali Klitschko in their WBC title fight.
Charles also faces a charge of assault for his involvement in the melee. Schlicht said more serious charges were reduced when police were unable to apprehend Haye despite searching for the boxer at his hotel.
Chisora and Charles were detained at Munich airport at 10:30 a.m. 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.
“I swear to God, David, I am going to shoot you. I am going to shoot you. I am going to physically shoot David Haye,” Chisora was heard yelling as he claimed Haye hit him with a glass.
Chisora’s promoter Frank Warren called the brawl “ugly, horrible and disgraceful” but said it was not his boxer who threw the first punch.
“It was an embarrassment for British boxing,” Warren told Sky Sports News. “I would say they were total idiots.”
Chisora taunted Haye about losing the WBA belt to Klitschko’s younger brother Wladimir last July, leading to a heated exchange before Chisora knocked a bottle out of Haye’s hand and they came to blows.
Camera equipment went flying and reporters fled before security eventually managed to separate the men.
“You’ve really lost it this time,” Chisora told Haye.
