14 of 52: Fellow detainees grab onto a man, second left, and removed a wire he had around his neck that is tied to a vent, after he threatened to jump from a rooftop at the Villawood Detention Center in Sydney, Australia, Thursday, April 21, 2011. Rioters at the Australian immigration detention center set fire to several buildings, climbed onto rooftops and hurled tiles at officials who were scrambling on Thursday to bring the chaotic protest to an end. Up to 100 people being held at the detention center were involved in the riots, which began Wednesday night when two detainees climbed onto a roof, immigration officials said.
