Last week the Malay Mail printed claims that Soosay asked another official to hide documents during a review of AFC practices. The incident is alleged to have occurred three years ago, during disgraced former president Mohamed bin Hammam's time at the helm of the AFC.
"Asian Football Confederation General Secretary Dato' Alex Soosay was today suspended by the AFC following media allegations which have recently surfaced concerning a case in 2012," the AFC said in a statement.
"A video statement conducted as part of a FIFA investigation was passed to media recently and the AFC has now been able to verify its authenticity."
According to the Malay Mail, the video referenced in the statement is believed to be of a conversation that took place between AFC financial director Bryan Kuan Wee Hoong and FIFA investigator Michael John Pride in which Kuan mention's Soosay's request.
Soosay, who denies any wrongdoing, has been temporarily replaced by deputy general secretary Windsor John while the investigation is ongoing.
