By Leon Watson An Irishman wanted in the U.S. for allegedly being the world's biggest child porn dealer could go free, it emerged today. Irish authorities have revealed Eric Eoin Marques will not be prosecuted under their jurisdiction and may challenge an attempt by the U.S. to get him extradited. Last month the 28-year-old, who the FBI has accused of being  the 'largest facilitator of child porn on the planet', indicated he would plead guilty to a series of charges under Irish law. In court: Ireland's DPP has revealed Eric Eoin Marques, aged 28, will not be prosecuted. He is pictured here being led to the High Court in Dublin, Ireland
