Police raided the headquarters of the Paris 2024 Olympic organizing committee and its infrastructure partner on Tuesday as part of investigations into alleged misappropriation of public funds and favoritism, prosecutors said.

The Paris 2024 offices were raided, according to the national financial prosecutor’s office (PNF), as part of a preliminary inquiry begun in 2017 investigating contracts signed by the Summer Games’ organizing committee.

The headquarters of SOLIDEO, the public body responsible for delivering Olympic and Paralympic infrastructure, were also being searched amid a preliminary investigation dating back to 2022, following an audit by the French Anti-Corruption Agency, the PNF added.

“A search is currently under way at the headquarters of the Organising Committee,” Paris 2024 said in a statement. “Paris 2024 is cooperating fully with the investigators to facilitate their inquiries.”

Paris 2024 did not give any further details.

“We do not have anything else to share at the moment,” a spokesperson said.

The Olympics will be held from July 26-Aug. 11 with the Paralympic Games taking place from Aug. 28-Sept. 6.
