UPDATE 11:00 p.m. ET:
The U.S. Olympic Committee has issued an apology to Rio for the ordeal involving swimmer Ryan Lochte and three others who reported being robbed at gunpoint over the weekend in Brazil.
"The behavior of these athletes is not acceptable, nor does it represent the values of Team USA or the conduct of the vast majority of its member," USOC CEO Scott Blackmun said, according to CNN.
Brazilian police have said the American athletes fabricated their story, accusing the swimmers of vandalizing a local gas station.

Police in Rio de Janeiro recommended Thursday that U.S. Olympic swimmers Ryan Lochte and James Feigan be indicted following false reporting of a crime, a civil police spokesperson told ABC News.
According to Yahoo Sports, Brazilian police authorities said Lochte, Feigan and two other U.S. swimmers did have a gun pointed toward them by a security officer after vandalizing a gas station bathroom, but said the athletes were not victims of a robbery.
At least one of the swimmers vandalized the bathroom after the four left a party Sunday night, according to Rio's Civil Police Chief Fernando Veloso. Police said the men broke mirrors and damaged other things in the restroom. The security officer reportedly pulled a gun over concerns about the swimmers' size and intoxication level.
Should the group of swimmers — which included Gunnar Bentz and Jack Conger — be found guilty of providing false testimony, they will likely have to pay a fine, but would not face jail time, police said. Local authorities denied reports that the athletes had already been indicted, NBC News reported.
One of the swimmers told investigators the group was not robbed, confirming gas station employees' recollection of the event, according to NBC News. Conger and Bentz left the police station Thursday night.
However, Feigan stood by his earlier story, telling the San Antonio Express-News Thursday that the group was, in fact, burglarized. Lochte, for his part, also maintained his original story, telling TMZ the video circulating in the news was edited to remove a portion of the altercation.
But several fellow athletes and people associated with USA Swimming have pushed back against Lochte's allegations as Team USA prepares for backlash against the Olympian and the U.S. organization. Lochte returned to the U.S. late Tuesday, but Feigen, Bentz and Conger have been detained in Brazil.
The three swimmers are "cooperating with authorities and in the process of scheduling a time and place today to provide further statements to the Brazilian authorities," U.S. Olympic Committee spokesman Patrick Sandusky said in a statement Thursday. "All are represented by counsel and being appropriately supported by the USOC and the U.S. Consulate in Rio."
Lochte and Feigan initially filed a report with police claiming they were the victims of an armed robbery. The incident sparked a rash of concern about safety in the Olympic city, but Brazilian authorities have failed to find much evidence to back up the athlete's story.
In a phone interview with NBC's Matt Lauer, Lochte stood by most of his story, but did revise his previous claim about the gun, saying it was not actually held up to his forehead.
A Brazilian judge ordered Lochte and Feigan to surrender their passports early Wednesday morning as part of the investigation into the alleged robbery. Lochte, however, was already back in the United States. Though they cleared customs, Bentz and Conger were detained by authorities Wednesday at the Rio de Janeiro International Airport as they were attempting to fly home.
