BRAZILIAN police have sought to seize the passport of John Delaney, as well as the passports of five other OCI officials.
Police in Rio de Janeiro arrived early on Sunday morning (August 21) at the Olympic Council of Ireland offices and accommodation in the Olympic Village.
According to a statement by the OCI, the police were met by three OCI personnel and, while no arrests were made, police took possession of their passports, mobile phones and laptops.
The Irish Post can confirm that the passports, laptops and mobile phones seized belonged to Mr Kevin Kilty, OCI Honorable Treasurer and Chef de Mission; Mr Stephen Martin, OCI CEO; and Dermot Henihan OCI General Secretary.
Brazilian police have also sought to take possession of passports belonged to three more OCI officials, Mr John Delaney, Chief Executive of the Football Association of Ireland and OCI Vice President; Mr Willie O'Brien, the interim President of the OCI; and Linda O'Reilly, the personal assistant to the OCI Presidency.
A number of unused official Olympic tickets, which were allocated to the OCI and had been made available for athletes families and were in the possession of the OCI personnel, were also seized on Sunday.
Mr Kilty, Mr Martin and Mr Henihan will present themselves for questioning on Tuesday (August 23) at a local police station.
Mr Delaney, Mr O'Brien and Ms O'Reilly, whose passports are being sought by Brazilian authorities, are all currently in Ireland.
Mr O'Brien who had been in attendance at the Games in Rio, is understood to have arrived back in Ireland on Sunday, (August 21).
The seizure of passports is the latest in the ticket touting scandal.
Earlier this month, Irishman Kevin Mallon was arrested in Rio for illegally reselling tickets to the Olympic opening and closing ceremony.
His arrest spawned an international investigation into ticket sales and the Olympic Council of Ireland, culminating in the arrest and subsequent detainment of former OCI President Pat Hickey.
At a press conference following his arrest, Brazilian police said they found evidence of emails and messages between Mr Hickey and Marcus Evans, who owns the hospitality company THG for which Mr Mallon works.
His passport, laptop and Olympic accreditations were seized.
Mr Hickey and Mr Mallon are both detained at the Bangu 10 prison in Rio de Janeiro, a maximum security facility.
While Mr Mallon and Mr Hickey are currently the only people being detained for this ticketing scandal, seven more arrest warrants have also been issued.
The arrest warrants, issued by Brazilian authorities at a bail hearing for Mr Mallon last week, are for THG directors, Marcus Evans, Maarten Van Os, Martin Studd and Irishman David Patrick Gilmore.
The directors of Pro10, the authorised ticket reseller for the OCI based in Lucan, west Dublin, also had warrants issued for their arrests at the press conference after Pat Hickey's arrest last week.
The arrest warrants were listed for Michael Glynn, Ken Murray and Eamon Collins.
