RIO DE JANEIRO — Brazilian police charged American swimmer Ryan Lochte with filing a false robbery report over an incident during the Olympics in Rio de Janeiro.

A police statement Thursday said Lochte will be informed in the United States so he can decide whether to introduce a defense in Brazil. The indictment will be sent to the International Olympic Committee’s ethics commission.

Lochte initially said he and fellow swimmers Jack Conger, Gunnar Bentz and Jimmy Feigen were robbed at gunpoint in a taxi by men with a police badge as they returned to the Olympic Village from a party. But security video suggested the four actually faced security guards after vandalizing a gas station restroom.

Lochte has since acknowledged he was highly intoxicated and his behavior led to the confrontation.

Rio police began questioning two of Ireland’s top Olympic executives in a Summer Games ticket-scalping probe that has already ensnared the highest official.

Olympic Council of Ireland’s team leader, Kevin Kilty, and chief executive, Stephen Martin, arrived at police headquarters wearing the Ireland team uniform.

“We are here to fully cooperate. That’s all I can say at the moment,” Kilty said.

Secretary General Dermot Henihan spoke to investigators Tuesday but they ruled out his involvement in the scheme, saying there was no evidence that indicated wrongdoing on his part.

But Rio police suspect that the highest-ranking members of the OCI plotted with businessmen to help transfer tickets to an unauthorized vendor who would sell them for high fees disguised as hospitality services.

The National Olympic Committee of Kenya was disbanded by the government amid investigations into alleged mismanagement of the country’s team at the Rio Olympics.

Those problems included a new doping scandal, ineligible athletes, missing plane tickets, and bad blood between the track and field federation and the national Olympic committee.

Despite the problems, Kenya had its best Olympic performance in Rio, winning six golds, six silvers and a bronze medal, and finishing 15th overall in the gold medal table.
