The International Olympic Committee said it has not received any request from Brazilian police for information concerning an investigation into a ticket-scalping scheme during the Summer Games in Rio de Janeiro.
On Thursday, police in Rio said they wanted IOC president Thomas Bach to explain why the Olympic Council of Ireland received 296 more tickets after exchanges between Mr Bach and high-ranking IOC member Patrick Hickey, who is facing charges in Brazil for ticket scalping, conspiracy, and ambush marketing in a case that emerged during the Games.
The IOC said: "Neither the IOC nor the IOC President have been contacted by any Brazilian authority concerning a request for information."
The IOC said it would not comment further because it is "an ongoing legal procedure."
The Olympic Council of Ireland's Crisis Management Sub Committee has appointed Deloitte to conduct an independent review of the OCI's governance arrangements.
The OCI says Deloitte will review the Memorandum and Articles of Association and the Constitution and will make recommendations on changes.
Deloitte is to prepare a draft report for the OCI Executive Committee within a month, and any proposed changes will then be put to an EGM.
