Pat Hickey arrest in Rio: What we know so far
The President of the Irish Olympic Council Pat Hickey has been arrested in Rio in relation to Brazilian authorities' ticket touting investigation.
The IOC chief was reportedly lifted at his accommodation in the Barra da Tijuca neighbourhood of the Brazilian city. The journalist Jamil Chade, who broke the story, said Mr Hickey was taken to hospital "as a precaution because of his age".
It is the latest twist in a scandal that erupted last week with the arrest of Irishman Kevin James Mallon in the Brazilian city.
Here is what we know so far:
May 12, 2015
PRO10 Sports Management is registered as a corporate body.
December 1, 2015
Team Ireland announces online that PRO10 will be its Authorised Ticket Reseller (ATR) for the Olympic Games in Rio, despite the company being in existence for less than seven months. The THG Group had been ATR for the previous two Games in London 2012 and Sochi 2014.
August 5, 2016
Dubliner Kevin Mallon, a director at THG, is arrested by Brazilian authorities in connection with alleged ticket touting. Some 781 tickets which were earmarked for the Olympic Council of Ireland (OCI) were confiscated.
The OCI releases a statement insisting that it has "no knowledge" of Mr Mallon, despite dealing directly with his company for two separate Olympic Games. It says it will be launching an investigation with PRO10.
PRO10 releases a statement to say that Mr Mallon was distributing tickets on its behalf in Rio as it did not have a member of staff in Brazil. Both PRO10 and THG insist that Mr Mallon was doing this voluntarily.
Sports Minister Shane Ross meets OCI president Pat Hickey to discuss the scandal, but is stonewalled on any of the details of the relationship between the OCI and PRO10.
A spokesman for THG admits there was a commercial relationship between the company and PRO10 which meant it had purchased other tickets from the ATR but would not disclose the number of tickets.
President of the OCI Pat Hickey is arrested in his room at the Barra de Tijuca hotel in Rio. Local press is reporting that Mr Hickey became ill after the arrest and had to be taken to hospital Samaritano, in Barra.
