French investigators think the vote to give Rio the 2016 Olympic Games may have been rigged with the help of Senegalese marketing consultant Papa Massata Diack, a paper in France is reporting.
Papa Diack is the son of former International Olympic Committee (IOC) member and president of athletics’ governing body Lamine Diack, who is currently being held in France on corruption charges.
According to French newspaper Le Monde, a Brazilian businessman paid $1.5m (£1.2m) to Papa Diack days before the host city was chosen.
“The French justice suspects that this money may have been used to influence the votes,” the paper says.
Rio 2016 organizers say the vote was “clean”. The Brazilian city won the right to host the Games by 66 votes to 32.
The newspaper says investigators have established that a holding company belonging to the Brazilian businessman paid the money to a company set up by Papa Diack.
Mr Diack is banned for life from athletics for alleged corruption, and Interpol has issued a “red notice” for his arrest.
He is accused of blackmailing athletes who failed drug tests but has denied any wrongdoing and Senegal has refused to extradite him to France.
