The court heard security staff had no way of knowing if the man had COVID-19. The security guard told Chan to leave and that he would not be permitted to attend court that day. Chan returned about an hour later, refusing to leave. The court heard Chan became aggressive and told the security guard: I m going to kick your head in, I m a kickboxing champion . Police were called and Chan was arrested. Chan was also charged with breaching bail, driving without a licence and possessing dangerous drugs. Magistrate Turner said the offences were serious. You told them you were a kickboxing champion, true sporting champions do not kick people in public, true sporting champions ensure they keep their skills for the appropriate sporting tournament, she said.
