French authorities are probing a payment of 2.8 million Singapore dollars (2 million US dollars) linked to Tokyo's successful bid for the 2020 Olympics.
The financial prosecutor's office said in a statement the payment was made in two instalments from a bank in Tokyo to the Black Tidings company in Singapore into an account linked to the son of former world athletics federation IAAF supremo Lamine Diack, and marked "Tokyo 2020 Olympic Game bid."
French authorities have been probing the Diacks on corruption allegations since last year, and Diack's son, Papa Massata Diack, is sought by Interpol. The separate probe on the Olympic host city election started on December 24, 2015, based on evidence and information gathered by then.
Lamine Diack was a member of the International Olympic Committee (IOC) when Tokyo was elected 2020 host by the IOC in September 2013 over Madrid and Istanbul. The payments to Black Tidings were made in July and October 2013.
