SAO PAULO, Sept 22 (Reuters) - Brazilian police arrested former Finance Minister Guido Mantega on Thursday as part of a sweeping corruption investigation into political kickbacks on contracts at state oil company Petrobras, according to a source close to the former minister.
Mantega served as finance minister for nearly a decade under former presidents Luiz Inacio Lula da Silva and Dilma Rousseff, steering Latin America's largest economy during most of the leftist Workers Party's 13 years in power. Attorneys for Mantega did not immediately respond to a request for comment.
