Michel Platini, former UEFA president, was arrested on Tuesday as part of the investigation into the awarding of the World Cup to Qatar, and held at the premises of the Anti-Corruption Office of the Judicial Police.
After being questioned, Platini said that he is innocent of all charges over the awarding of the 2022 World Cup.
He had been suspended from any football activities for four years over a $2 million payment he received from FIFA.
He led UEFA from 2007 to 2015, and was the heir apparent to take over from Sepp Blatter, until both men were swept out of the sport in the wake of the massive corruption scandal from which it is still reeling.
The interrogation by investigators raises questions over the controversial decision to host the upcoming World Cup in Qatar, a Middle Eastern nation which lacks the infrastructure or sporting tradition of previous host countries. Qatari organizers have repeatedly denied allegations of wrongdoing in the bidding process.
High temperatures in Qatar have since forced FIFA to move the tournament to the winter for the first time ever, while watchdogs have criticized the Qatari government's human rights record, the country's ban on homosexuality and the welfare of workers involved in preparing stadiums for the tournament.
