Police in Rio are questioning two of Ireland’s top Olympic executives in a ticket-scalping probe that has already ensnared the highest official.
The Olympic Council of Ireland’s team leader Kevin Kilty and chief executive Stephen Martin arrived at police headquarters wearing the Irish team uniform.
Mr Martin is from Bangor, Co Down.
Secretary general Dermot Henihan spoke to investigators on Tuesday, but they ruled out his involvement in the scheme.
The officials’ passports, phones and laptops were seized in an Olympic Village raid hours before the closing ceremony.
OCI president Patrick Hickey was arrested last week and is being held in Rio’s Bangu prison complex.
Authorities say a company called Pro 10 Sports Management was created to help transfer tickets between the OCI and an unauthorised vendor who would sell them for high fees.
