Patrick Hickey, a senior member of the International Olympic Committee, has temporarily stood down from all his roles after his arrest in Rio over allegations of illegal ticket sales.
国际奥委会高级官员帕特里克·希基暂被停止一切职务，他因涉嫌非法售卖奥运门票在里约被捕。
The Irishman, 71, was taken to hospital following his arrest, after requesting medical attention.
Brazilian police claim he was involved in a scheme to resell Olympic tickets at higher than their face value.
They said the scheme could have had profits of 10m reals (£2.4m; $3.1m).
Mr Hickey will be replaced as president of the European Olympic Committees - the body which brings together the 50 national committees across the continent - by his deputy Janez Kocijancic.
The Olympic Council of Ireland (OCI) said in a statement that Mr Hickey was stepping aside "until this matter is fully resolved" and would continue to co-operate and assist with all enquiries. 英语新闻
