FIFA says former President Sepp Blatter and two other ex-officials have awarded themselves pay rises, bonuses, and other incentives worth $80 million over five years.
Football's governing body said on June 3 that an internal investigation had revealed that the trio -- which includes ex-Secretary-General Jerome Valcke and former Finance Director Markus Kattner -- was involved in a "coordinated attempt" to "enrich themselves" between 2011 and 2015.
FIFA said the evidence uncovered by its internal investigation would be shared with Swiss and U.S. prosecutors.
Blatter's lawyer said his payment arrangements at FIFA were "proper and fair."
FIFA has been in turmoil since May 2015, when a U.S. probe exposed widespread corruption at the top of the organization.
Over the past year, Blatter, his number two Valcke, and Kattner have been fired or booted out of office for suspected criminal mismanagement of FIFA money.
