A judge allowed Mr Hickey to leave on medical grounds, after paying a €400,000 bail
Pat Hickey is reported to be on his way home from Brazil.
According to The Irish Times, Mr Hickey - who stepped aside as President of the Olympic Council of Ireland (OCI) following his arrest in Brazil - went through security at Rio’s international airport at around 8.15pm local time (10.15pm Irish time) last night.
The 71-year-old had been in Rio for four months awaiting trial as part of an investigation into alleged ticket touting.
However a judge allowed him leave on medical grounds, after paying a €400,000 bail bond. He has also been ordered to continue to comply with the legal process.
He was granted a loan by the Association of National Olympic Committees (ANOC) to pay the bail required to get his passport back.
In a statement yesterday, the OCI confirmed that Mr Hickey will not be a candidate for President in its February elections for new officers and an executive committee.
"Pat Hickey has repeatedly advised in the past year prior to the Rio Games 2016 he would be finishing his term of office after the Games," the organisation said.
