The British Boxing Board of Control have confirmed they are investigating the behaviour of Dereck Chisora before, during and after his points defeat to WBC heavyweight champion Vitali Klitschko in Munich on Saturday night.
Former WBA champion David Haye was still wanted for questioning by German police on Monday following his shocking post-fight press conference brawl with Chisora, who arrived back in England on Sunday night after being freed without charge following the unsavoury scenes at the Olympiahalle venue.
Chisora also courted controversy with his pre-fight antics, slapping his 40-year-old opponent at the weigh-in and then spitting water into brother Wladimir's face in the ring.
A BBBC statement from general secretary Robert Smith read: "The British Boxing Board of Control are looking at the behaviour of British Boxing Board of Control-licensed boxer Dereck Chisora prior, during and after his contest for the World Boxing Council heavyweight championship against Vitali Klitschko on Saturday, 18 February 2012 in Munich.
"The stewards will be considering Mr Chisora under regulation 25 (misconduct) and a further statement will be issued once the stewards have decided on what action will be taken.
"With regard to Mr David Haye, Mr Haye is not a licensed boxer with the British Boxing Board of Control and therefore no longer under the jurisdiction of the British Boxing Board of Control."
