On 5 August, the day of the 2016 Summer Olympics opening ceremony, police in Rio de Janeiro arrested two people for attempted illegal resale of hundreds of tickets allocated to the Olympic Council of Ireland (OCI). The scandal precipitated the dramatic arrest of OCI president Pat Hickey, while in a hotel room assigned to his son. Hickey immediately resigned, as well as relinquishing his membership of the International Olympic Committee, his role as president of the European Olympic Committees and his role as vice-president of the Association of National Olympic Committees.
