The Head of Japan's Olympic committee is under investigation by French authorities who suspect he may have paid bribes to secure his country's hosting of the 2020 games.
A judicial source in France told Reuters that Tsunekazu Takeda was indicted last month for corruption.
Takeda denies it.
A former Olympic athlete himself, he said in Tokyo that no improper actions had taken place in connection with Japan's bid.
He also said that had not been indicted by French authorities.
French law has two levels of indictment -- the base level means he is a suspect but a full indictment only comes if it turns into a court case.
The International Olympic Committee says it's in close contact with French authorities.
And added its ethics committee has opened a case file and would meet later on Friday (January 11).
This case is tied to an investigation that started in 2016, when French prosecutors announced they were looking into more than $2 million worth of payments made by the Japanese bidding committee to a Singapore consultancy firm - Black Tidings.
In 2017, Takeda and others were voluntarily questioned by Japanese prosecutors at the request of French authorities.
Wrongdoing was denied by the whole group.
He has been president of the Japanese Olympic Committee for 17 years.
