The International Association of Athletics Federations said on Wednesday it was fully cooperating with a French investigation into allegations concerning its anti-doping rules.
In a statement issued after the French prosecutor's office confirmed that the IAAF's former head had been put under formal investigation as part of a corruption and doping probe, the sport's world governing body issued a statement saying:
"The IAAF is fully cooperating with all investigations as it has been from the beginning of the process.
