Football’s governing body, Fifa, has submitted a report to Swiss authorities following a 22-month long inquiry into allegations of corruption and criminal misconduct, reported Reuters.

The investigation began after several officials were summoned in the United States in 2015 for corruption-related charges as Fifa faced the worst scandal in its 113-year history.

Fifa’s ethics committee has since banned former president Sepp Blatter for six years and former secretary general Jerome Valcke for 10 years on alleged corruption charges. Blatter is currently under criminal investigation in Switzerland.

Fifa revealed that it went through more than 2.5 million documents, adding that the final report shared with Swiss authorities ran to 1,300 pages, including 20,000 pages of “exhibits”.

“Fifa is committed to conducting a thorough and comprehensive investigation of the facts so we could hold wrongdoers within football accountable and cooperate with the authorities,” Fifa president Gianni Infantino said.

“Swiss prosecutors will continue to pursue those who enriched themselves and abused their positions of trust in football,” Infantino added. Fifa said its report would be available to US investigators.
