Friday 17th May, 2009, Mairead Maguire, Nobel Peace laureate, was detained on her entry into Houston Airport, USA, by Homeland Security Immigration. Maguire was on her way home to Northern Ireland, after attending a 3 day conference in Guatemala, which was hosted by herself and three Sister Nobel Peace Laureates, Rigoberta Menchu, Jody Williams, and Shirin Ebadi. 150 women activists from around the World attended the Nobel Womens' Conference to discuss, 'Redefining Democracy, Human Rights and Peace.' Maguire was held for two hours, during which she was questioned, fingerprinted, photographed and questioned again. This resulted in her missing her flight.
