Mexico wants a large sum of money back from former Mexican security official Genaro García Luna, who is on trial in New York, AP reports.
President Andres Manuel Lopez Obrador said his government wants to return the $700 million García Luna accumulated through corruption.
Foreign Minister Marcelo Ebrard said Mexico filed the lawsuit in Florida, where García Luna lived after leaving Mexico.
García Luna, the country's former top security officer, is on trial in New York on charges that he received millions of dollars in bribes to allow the notorious Sinaloa cartel to operate with impunity, sending tons of cocaine to the United States.
He served as secretary of public security under then-President Felipe Calderon from 2006 to 2012. His attorneys say he was a legitimate businessman who counseled in Florida before he was arrested in 2019.
Lopez Obrador has long complained that when corrupt politicians and drug dealers are convicted in the United States, the U.S. gets their fortunes, which were often largely gained in Mexico.
