(CNN) Disgraced former UEFA President Michel Platini has been taken into custody as part of a corruption investigation over the awarding of the 2022 World Cup to Qatar, the French financial prosecutor's spokesperson told CNN on Tuesday.

The ex-boss of Europe's soccer governing body had been serving a four-year ban from the sport since 2015, over a $2 million payment he received from FIFA.

He has been brought in for questioning but has not been arrested or charged with a crime, the spokesperson said.

The former French soccer legend led UEFA from 2007 to 2015, and was the heir apparent to take over from FIFA head 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.

Platini's interrogation by investigators again raises questions over the controversial decision to host the upcoming World Cup in Qatar, a small but wealthy 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.
