French investigators suspect Tokyo Olympics corruption - sources

French investigators suspect that payments made to the son of disgraced athletics supremo Lamine Diack were to get support for Tokyo's 2020 Olympics bid, a source close to the inquiry told AFP on Thursday. Some 1.3 million euros ($1.5 million) paid to a company owned by Papa Missata Diack is at the centre of the suspicions. The Japanese government insisted earlier on Thursday that the Tokyo bid was "clean".
