Belarusian sprinter Krystsina Tsimanouskaya was safe in Vienna on Wednesday, Austrian officials said, after she flew in from Tokyo under Polish diplomatic protection three days since refusing her team’s order to go home early from the Olympics.

The apparent Cold War-style defection of an athlete has been one of the major stories of the Games and could further isolate Belarus, which is under western sanctions after President Alexander Lukashenko’s crackdown on opponents since last year.

After spending two nights in Poland’s embassy, the 24-year-old sprinter walked onto a plane at Tokyo’s Narita airport wearing wearing jeans, a blue blouse and sunglasses with “I RUN CLEAN” written on them.

“She is safe and is doing well under the circumstances,” Magnus Brunner, Austria’s deputy environment minister, told reporters after her Austrian Airlines flight touched down in Vienna. “She is naturally worried and excited and nervous about what will happen next for her.”

Tsimanouskaya was expected to travel on to Poland, which has granted her a humanitarian visa and another to her husband to join her.

The sprinter caused a furore on Sunday when she said coaches had demanded she pack her bags at the Olympic village and taken her to the airport against her wishes, ordering her home because she had criticised them. She refused to board the flight and sought protection of Japanese police. “I will not return to Belarus,” she told Reuters at the time.

The Belarus National Olympic Committee did not respond to a request for comment on Wednesday. Previously, it said coaches had decided to withdraw Tsimanouskaya from the Games on doctors’ advice.

She was initially due to fly directly to Warsaw on Wednesday, but a Polish government source said she was switched at the last minute to the Vienna flight after news of her itinerary became public.
