Europe's top Olympic official arrested in ticket sale probe

Mr Hickey, 71, is suspected by police of being linked to an international scheme to illegally pass Olympic tickets to touts who were reselling them at well above their original price.

He has temporarily stepped down from his position as IOC executive board member and all other Olympic roles "in light of this morning's developments and his ill health" until the matter is resolved, the Olympic Council of Ireland said in a statement.

Justin Rose wins Olympic Golf event

Rose, who hit a hole in one on his first day, carded a final round four-under-par 67 to beat Sweden's Henrik Stenson by two shots in a competition that went all the way to the final putts. American Matt Kuchar claimed bronze.

"I've been thinking about Rio for a long, long time," Rose said. "To come out of it with a medal is incredible, and to come out of it with gold, unbelievable."
