Dereck Chisora caused a stir at Dillian Whyte's latest press conference and the pair had to be kept apart as they traded words.
Heavyweights Chisora (25-6-KO17) and Whyte (16-1-KO13) have traded insults over social media in the past but Chisora's arrival in the lobby of a hotel threatened to turn their disagreement physical before security moved in to usher the north Londoner away.
Whyte signed for Matchroom earlier in the week as he prepares to make his comeback from shoulder surgery on the undercard of Anthony Joshua v Dominic Breazeale on June 25 - live on Sky Sports Box Office - and was holding a press conference to discuss the news.
The Brixton fighter hadn't banked on the attendance of Chisora, who recently fell short in a bid to become European champion when he was outpointed by fellow former world title challenger Kubrat Pulev.
With the insults flying and Whyte threatening to end Chisora's career in the ring, onlookers were left stunned.
