After weighing in at 17 stone 3lb, Chisora butted heads with the 6ft 7in champion before delivering a hard slap to the left cheek with his right hand.
The two men were pulled apart, with a furious Klitschko, who had weighed in three pounds heavier than his opponent, left nursing a red mark on his cheek. The pair exchanged profanities before Chisora was whisked to safety out of the Karstadt Sports Store.
Klitschko, who weighed in at 17st 6lb, yelled at the British fighter: “You are f—– now, Chisora, you are now really f—–!”
Chisora swore back at him before disappearing down a back stairwell, heard screaming: “Where’s my driver? Get me the f— out of here.”.

A livid Klitschko told onlookers that he was unsurprised at the behaviour of Chisora, who was found guilty 14 months ago of attacking his former girlfriend.
“What can you expect from a guy who hits his girlfriend? I’m glad he has agreed to fight a man again,” he said. “Now I’m going to give him a lesson when we get in there.”
The incident may boost the ratings for the fight, but Chisora has played into Klitschko’s hands. After the attack, Ladbrokes were offering odds of 25-1 for Chisora to be knocked out before he even lands a punch.
But Charles and Chisora have talked this week about great upsets, among them Lloyd Honeyghan defeating the unbeaten Don Curry, regarded as the No 1 pound-for-pound fighter at the time, in 1986.
They have discussed Buster Douglas having Tyson fumbling on all fours in a befuddled search for his gumshield in 1990, and Hasim Rahman flooring Lennox Lewis in 2001.
Klitschko, in his 10th WBC title defence, to win inside four rounds, by knockout.
