Papa Massata Diack, son of the former president of the International Association of Athletics Federations (IAAF), has denied allegations that he received money from the Tokyo Olympic bid team through a Singapore bank account in return for helping Tokyo land the 2020 Games.

"I haven't got any money," Papa Massata said during an interview Saturday in Dakar.

He was speaking after French prosecutors launched an investigation into Tokyo's bidding campaign over its payment of some 2.8 million Singapore dollars (around $2 million) to an account of a Singaporean consulting firm, which British newspaper The Guardian reported has a link to Papa Massata.
