RIO DE JANEIRO -- Police investigating reports that American swimmer Ryan Lochte and three of his teammates were robbed at gunpoint in a taxi so far have found little evidence supporting the account, and say the swimmers were unable to provide key details in police interviews.A police official with knowledge of the investigation told The Associated Press that police cannot find their taxi driver or witnesses. The official spoke on condition of anonymity because the investigation is ongoing.Lochtes attorney, Jeff Ostrow, said there was no question the robbery happened and that Lochte had 24-hour security hired after the incident. He had been staying in his hotel room and intended to go back to the U.S. soon.This happened the way he described it, Ostrow said.According to statements from Lochte and the United States Olympic Committee, the swimmers were returning to the athletes village by taxi after a night out at the French Olympic teams hospitality house in the Rodrigo de Freitas area in the upscale south zone of the city. The outing was several hours after Olympic swimming ended Saturday night at the Rio Games.Traveling with Lochte were Gunnar Bentz, Jack Conger and Jimmy Feigen. Lochte swam in two events at the Rio Games, winning gold in the 4x200-meter freestyle relay. He is a 12-time Olympic medalist.The group did not call police, authorities said, and officers began investigating once they saw media reports in which Lochtes mother spoke about the robbery. Police interviewed Lochte and one other swimmer, who said they had been intoxicated and could not remember what type and color of taxi they rode in or where the robbery happened, the police official said. The swimmers also could not say what time the events occurred.Later in the day, Lochte described the incident to NBCs Today show .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 said. 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 didnt do anything wrong, so -- Im 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.Word of the robbery initially created confusion between Olympic and U.S. officials. An International Olympic Committee spokesman at first said reports of the robbery were absolutely not true, then reversed himself, apologized and said he was relying on initial information from the USOC that was wrong.Lochte told USA Today that he and his teammates didnt initially tell the U.S. Olympic officials about the robbery because we were afraid wed get in trouble.Scott Leightman, a spokesman for USA Swimming, said the organization has no further comment and referred back to a statement issued Sunday by the USOC that briefly described the robbery and said that all four swimmers were safe and cooperating with authorities.The incident got attention in part because of fears around street crime at the games. Athletes and visitors have been told to use caution around the Olympics. Street crime was a major concern of Olympic organizers, and Brazil deployed 85,000 soldiers and police to secure the games, twice as many as Britain used during the 2012 London Olympics.Authorities are treating the swimmers as victims and continuing to investigate, looking for security footage at the French hospitality house and nearby gas stations to build a timeline of the night. Security footage from the athletes village obtained by police shows the swimmers arriving at 6:56 a.m. on Sunday morning, the official said.Rio police commonly struggle to obtain information while investigating street crimes in Brazil as they encounter dozens of robberies a day in the violence-ridden city and lack the resources to get to the bottom of every case. Many such crimes dont even get reported by victims.Fake police stops like the one reported by Lochte happen in Rio, but are not common in that area, police say. They are typically a bigger problem in the poorer cities where police are less present.Lochte signed a statement on Monday confirming the facts he provided, his attorney said.Ryan was a hundred percent cooperative and fully available when they reached out to us for an interview, Ostrow said. He added: It doesnt behoove Ryan and anyone else to make up a story. Discount Air Max . The winner Saturday will remain in the elite 10-team field next year.

Like so many other veterans, he had to grind his way through exhibition games in training camp, gradually moving from 11 points in his first preseason game, to 15, to 20 and finally to 34 in the final warm-up game last week.His patience was rewarded Wednesday night as the Olympic gold medalist had 40 points in the Toronto Raptors 109-91 season-opening victory over the Detroit Pistons, his third career 40-point outing and just two off his career high.Preseason (stunk), he said. But youve got to do it and now the real deal is here and youre just trying to catch a rhythm.DeRozan made a career-high 17 field goals on 27 shots and was a perfect 6 for 6 from the free throw line, while Jonas Valanciunas was 10 for 15 from the field to go along with 11 rebounds. Valanciunas previous career high was 31, also against the Pistons, on Jan. 12, 2015.According to Elias Sports Bureau, the duo became the first teammates in NBA history with a 40-point game and a 30-point game in a season opener. DeRozan also broke Vince Carters opening-night franchise record of 39 points, set against the-then New Jersey Nets in 2003.I never keep track, DeRozan said of his record-breaking exploits. Somebody always informs me after the game.Valanciunas also played down his accomplishment, despite registering his second career 30-point game, as the Raptors led from the 5:13 mark of the first quarter and never looked back.Eighty-one games to go, he said. We should not get too excited; this is just the start.Tobias Harris had 22 points and Marcus Morris had 17 points and nine rebounds for the Pistons, who lost for the eighth time in their last 11 games against Toronto.Coach Stan Van Gundy was particularly irked with his teams defensive play in losing their season opener for the fifth time in seven years, especially the fact that Detroit was outrebounded 51-40. It didnt help that center Andre Drummond left the court after getting elbowed in the jaw by Valanciunas early in the first quarter, though he later returned.The rebounding was a major concern, he said. (Giving up) 54 points in the paint was a major concern and 29 frree throw attempts, so that just means the team took it right at you.ddddddddddddTIP-INSPistons: Henry Ellenson, Detroits first-round draft pick last June (18th overall) went scoreless in 2:10 of play, while second-round selection Michael Gbinije (49th overall), had two points in 2:10.Raptors: C Lucas Nogueira (ankle) sat out. .

Siakam became the first Toronto rookie to start a season opener since Valanciunas in 2012, and rose to the occasion, hauling in nine rebounds to go along with four points in 21 minutes.UNITED NATIONSWith the draft-day additions of Poeltl (Austria) and Siakam (Cameroon), Torontos roster has players representing five countries other than the United States.
