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). One of the two, Kevin Mallon, was an executive with THG Sports, which was the OCI's authorised ticket reseller (ATR) in 2012 but not 2016; the OCI denied any involvement. Pro 10 Sports Management, the OCI's 2016 ATR, said the man arrested was working as their agent to distribute tickets which had been paid for legitimately.
