Special prosecutor Juan Francisco Sandoval, who said Colom was arrested on Tuesday, is looking into the questionable purchases of public buses for Guatemala City. The Transurbano is a public transport organization in Guatemala City run by the Guatemalan Integrated Bus System and promoted by the Guatemalan government during the 2008-2012 Colom administration, and by the Urban Bus Entrepreneurs Association. A typical case is Fuentes Knight, the president of Oxfam International, who is accused of taking part in the Transurbano corruption scheme when he was finance minister during the Alvaro Colom government.
Former President Alvaro Colom and his entire government cabinet were arrested for their alleged participation in a new corruption case investigated by CICIG and the MP. They were sent to preventive detention at the Mariscal Zavala Military Center.
