Comedian Chas Licciardello, dressed as al-Qaeda leader Osama bin Laden, is arrested by police outside US President George W. Bush's hotel during the Asia-Pacific Economic Cooperation (APEC) group forum in Sydney in this image taken from September 6, 2007 video footage. Television comedians penetrated tight security around an Asia-Pacific forum on Thursday, driving a fake motorcade unchallenged through two check points. Members of Australia's Chaser television comedy programme drove three cars, with motorcycle escorts, through the city centre, where thousands of police and high fences have been installed to protect world leaders.
