Sepp Blatter has reiterated that he has done "nothing illegal or improper" and has vowed to stay on as FIFA president.
The Swiss has previously stated that he will step aside prior to next February's election after world football's governing body was engulfed by a major corruption scandal.
It was announced last week that Blatter himself is now also under investigation on suspicion of criminal mismanagement and a separate claim of misappropriation.
However, the FIFA top boss has claimed in a statement released through his lawyers that he will remain in his current position, but did not specify exactly how long for.
"President Blatter spoke to FIFA staff today and informed the staff that he was cooperating with the authorities, reiterated that he had done nothing illegal or improper and stated that he would remain as president of FIFA," it read.
Blatter, who was re-elected as president earlier this year before announcing his intention to stand down, was accused of handing over "disloyal payment" to UEFA chief Michel Platini in 2011.
"On the Platini matter, president Blatter on Friday shared with the Swiss authorities the fact that Platini had a valuable employment relationship with FIFA serving as an advisor to the president beginning in 1998," the statement added.
"He explained to the prosecutors that the payments were valid compensation and nothing more and were properly accounted for within FIFA including the withholding of Social Security contributions."
Platini has not been accused of any wrongdoing and is expected to remain in the race to replace Blatter, should the 79-year-old step aside prior to next year's latest election.
