Michel Platini, the former head of European football association UEFA, was detained and questioned by French police on Tuesday over the awarding of the 2022 World Cup to Qatar.
The detention and questioning of the former French football star was first reported by French investigative website Mediapart.
Prosecutors in the investigation suspected corruption and bribery in the process of awarding the 2022 World Cup to the Gulf emirate of Qatar.
Platini fought to reduce an eight-year ban from football activities imposed by FIFA in the wake of the corruption scandal in 2015 and eventually saw his suspension reduced to four years, meaning he can return to the game in October.
