The searches coincided with the start of a two-day International Olympic Committee Executive Board on Tuesday to discuss a number of issues, including progress of Paris 2024 Games preparations.
"We are aware that there has been a search by police of the Paris 2024 headquarters today," an IOC spokesperson said. "We have been informed by Paris 2024 that they are cooperating fully with the authorities in this matter."
