Chris Overholt, head of the Canadian Olympic Committee, said the Korean police have now concluded their investigation and the "team members have been released".
"I have let my teammates, friends and my family down", Raine said.
The official, who did not identify the suspects by name, said the manager drove off with the auto before it was stopped by police.
William Ryan Raine, the ski cross high-performance director, called his actions "inexcusable" and apologized to the owner of the involved vehicle in his statement released by the Canadian Olympic Committee.
"We have a transport plan for every Games, we work hard at all of that to be ready for everything in the context of our participation here, so all those things are true, but again I'm not familiar enough with the circumstances enough to tell you what happened in this case".
Joss Whedon no longer directing Batgirl
James Viscardi of Comicbook and Umberto Gonzalez of The Wrap have voiced their opinions on Whedon's exit from Batgirl on Twitter . Whedon told The Hollywood Reporter in a statement that "it took me months to realize I really didn't have a story".
The athlete, identified as Dave Duncan by CBC, was accompanied by his wife and manager when they jumped in a parked Hummer that belonged to a 57-year-old tourist visiting the South Korean county for the Olympics, according to local reports.
Raine, according to police, was behind the wheel and allegedly had a blood-alcohol level more than three times the legal limit.
Duncan finished eighth in the ski cross in Pyeongchang, topping his 24th-placed finish in Sochi in 2014.
Canada are third in the overall rankings in Pyeongchang, with 11 gold medals, behind Norway and Germany.
A Canadian Olympian might have gone a little too far in his post-Olympic celebrations in PyeongChang. "We engaged in behavior that demonstrated poor judgment and was not up to the standards expected of us as members of the Canadian Olympic Team or as Canadians", the statement from David and Maja Margrethe Duncan read. He added: "We have information that individuals attached to our team were involved in the investigation and they're cooperating".
