RIO DE JANEIRO -- U.S. Olympic swimmer Ryan Lochte has apologized for his behavior related to a late-night incident at a Rio de Janeiro gas station, saying he should have been more "careful and candid" about how he described what happened.
Lochte said in a post on Instagram on Friday that he also was apologizing for his role in taking the focus away from other Olympic athletes.
The 12-time Olympic medalist reiterated his assertion that a stranger pointed a gun at him and demanded money to let him leave. Lochte had previously called it a robbery; Brazilian police said he and three other swimmers vandalized a gas station bathroom and were confronted by armed security guards.
"I accept responsibility for my role in this happening and have learned some valuable lessons," Lochte said on Instagram.
"We accept and appreciate his apology," said Mario Andrada, spokesman for the local organizers of the Rio Games.
Two of the other swimmers, Gunnar Bentz and Jack Conger, landed in Miami on Friday morning after being held in Brazil until they testified. The fourth swimmer, Jimmy Feigen, made a deal with a judge to make a $10,800 payment and left the country later Friday.
The drama surrounding the alleged robbery -- and the swimmers' ever-changing descriptions of it -- has shocked and angered Brazilians, who said it cast an unearned negative shadow on Rio and the Olympics at a time when the country is eager to prove it can host the Games safely. The story also dominated Olympic headlines, overshadowing the accomplishments of athletes who trained for years just to get to Rio. The saga was an embarrassment for the U.S. Olympic team, which has dominated in the medal count.
Andrada said 2.5 percent of the mentions on the @Rio2016 Twitter account since the beginning of the Games have been about the Lochte situation.
"There has already been too much said and too many valuable resources dedicated to what happened last weekend, so I hope we spend our time celebrating the great stories and performances of these Games," Lochte said.
Rapid developments early Friday came hours after police announced that Lochte and three of his teammates had not been held at gunpoint after a night of partying, as Lochte claimed. Instead, Brazilian police said the men, while intoxicated, vandalized a gas station bathroom and were questioned by armed guards before they paid for the damage and left.
"No robbery was committed against these athletes. They were not victims of the crimes they claimed," Civil Police Chief Fernando Veloso said at a news conference.
As Bentz and Conger flew home Thursday night, their attorney insisted they were witnesses only and had nothing to do with Lochte's story.
"They did not make any untruthful testimony. They did not lie in their statements," lawyer Sergio Riera told The Associated Press.
In excerpts of police interviews with Conger and Bentz, released Friday by the Rio de Janiero Civil Police to the media, both U.S. swimmers pointed a finger at Lochte as the instigator at the gas station. They said that while they were using the bathroom, Lochte pulled an advertising poster off the wall, creating a lot of noise.
Bentz, who swims for the University of Georgia, also released an apology through the university Friday night and gave a detailed account of Sunday's incident.
"I want to offer a sincere apology to the United States Olympic Committee, USA Swimming, the extraordinary women and men of Team USA, and the University of Georgia," Bentz said. "I regret this situation has drawn attention away from the Olympics, which have been hosted so incredibly well by Brazil and its citizens."
Bentz's statement mirrored the account he gave to police, and he admitted the swimmers relieved themselves on the back side of the gas station. He said that to his knowledge, there was no damage to the restroom or restroom door.
"Videos of this situation have been emerging the last several days. However, I am confident that some video angles have not been shown that would further substantiate my account. I also believe some scenes have been skipped over," he said.
One of the security guards at the gas station, in a statement to police obtained by ESPN Brasil on Friday, said that Lochte and Feigen tried to leave the area twice -- first with Conger and Bentz in a taxi that was seen on a videotape released Thursday, and later on foot alone. However, the guard said they realized their teammates had stayed behind, and they returned to the gas station.
The guard, who told police he recognized Lochte from his hair, said that Lochte was agitated and resisted, so the guard drew his gun at a 45-degree angle to the ground in an attempt to quiet Lochte. A second guard, he said, also pulled a gun at a 45-degree angle to back up his partner, and Lochte eventually sat down.
The guard also said that the swimmers cursed loudly as they left the taxi.
In the portions of the statements released Friday, neither Conger nor Bentz mentions the security guards drawing guns around them, though police did ask them about it.
A lawyer for Feigen said early Friday that the athlete reached an agreement with a judge in which he planned to donate 35,000 Brazilian reals ($10,800) to an "institution" and leave the country later in the day.
Attorney Breno Melaragno said that under the agreement, Feigen would make the donation, get his passport back and depart.
A Brazilian court statement late Friday said the fine had been paid and the passport returned. Feigen departed the Rio airport late Friday, according to the USOC, although Brazilian prosecutors made a last-ditch effort to increase the amount of money that Feigen would pay.
In a statement, prosecutors said they would appeal the judge's ruling on the fine and ask that Feigen pay $47,000 instead. If prosecutors win, Feigen would have to pay the fine if he ever wanted to return to Brazil.
Melaragno did not specify where the money will go, but the term "institution" can be taken to mean a charity. He said that under Brazilian law, a donation can be made to avoid criminal prosecution for minor offenses, but he did not say what charge was being contemplated.
Though police appear mostly finished with their probe, the case might be far from settled. Police have said authorities are considering charges of falsely reporting a crime and destruction of property, both of which can carry up to six months in jail or a fine.
Lochte's attorney, Jeff Ostrow, has insisted that Lochte's story wasn't made up and told The New York Times that the surveillance video corroborated the "primary elements" of Lochte's version of events.
"There was a uniformed person with a gun who forced them to hand over their money," Ostrow told the newspaper.
Teammate Michael Phelps, approached by E! on Friday, said he hadn't spoken to Lochte. Asked whether he thought Lochte would emerge from the situation unscathed, Phelps said: "We have good people taking care of it, so hopefully."
The saga began when Lochte said he and Conger, Bentz and Feigen were held at gunpoint and robbed several hours after the last Olympic swimming races ended. That claim started unraveling when police said that investigators could not find evidence to substantiate it.
Then security video reviewed by police confirmed the athletes vandalized parts of the gas station, leading to an encounter with station employees.
The video shows one of the swimmers pulling a sign off of a wall and dropping it onto the ground. A gas station worker then arrives and other workers inspect the damage. Veloso said the swimmers broke a door, a soap dispenser and a mirror.
The swimmers eventually talk with station workers and their cab leaves. In another sequence, the swimmers appear to briefly raise their hands while talking to someone and sit down on a curb.
After a few minutes, the swimmers stand up and appear to exchange something -- perhaps cash, as police said -- with one of the men.
The footage doesn't show a weapon, but a police official, speaking on condition of anonymity because the investigation was ongoing, said two guards pointed guns at the swimmers. Veloso said the guards did not use excessive force and would have been justified in drawing their weapons because the athletes "were conducting themselves in a violent way."
A station employee called police, and the guards and employees tried to get the swimmers and the taxi driver to stay until authorities arrived, some even offering to help interpret between English and Portuguese, Veloso said. But he said the athletes wanted to leave, so they paid 100 Brazilian reals (about U.S. $33) and $20 in U.S. currency and left.
Police said the swimmers had been unable to provide key details in early interviews, saying they had been intoxicated. The police official said officers grew suspicious when video showed the swimmers returning to the athletes' village wearing watches, which would have likely been taken in a robbery.
Bentz and Conger told police that they felt Lochte had lied about the situation in media interviews, according to text of the statements released by Rio police.
"We got pulled over, in the taxi, and these guys came out with a badge, a police badge, no lights, no nothing, just a police badge, and they pulled us over," Lochte told NBC's "Today" the morning after the incident. "They pulled out their guns, they told the other swimmers to get down on the ground -- they got down on the ground. I refused, I was like, 'We didn't do anything wrong, so -- I'm not getting down on the ground.'
"And then the guy pulled out his gun, he cocked it, put it to my forehead and he said, 'Get down,' and I put my hands up, I was like, 'Whatever.' He took our money, he took my wallet -- he left my cellphone, he left my credentials."
The debacle prompted both wild speculation and social media mockery, which quickly turned to scorn after the official account went public.
David Fleischer, a political scientist at the University of Brasilia, said the incident touched a nerve in Brazil because of the country's history and cases of people committing crimes while impersonating police.
"The story did have some sense of validity, but it didn't bear out and it made them look bad worldwide," he said.
That outrage was evident Thursday, as onlookers shouted "liars" and "shameful" at Bentz and Conger as they left a police station where they gave statements.
Lochte and the other swimmers could face sanctions from USA Swimming, including fines or suspension. The organization echoed Olympic officials in publicly expressing disappointment and pledging to further examine the matter.
"We apologize to our hosts in Rio and the people of Brazil for this distracting ordeal in the midst of what should rightly be a celebration of excellence," the U.S. Olympic Committee said.
