A Belarusian sprinter refused to get on a flight from Tokyo on Sunday after being taken to the airport against her wishes by her team following her complaints about national coaching staff at the Olympic Games.

Krystsina Tsimanouskaya, 24, was still at Tokyo's Haneda airport in the early hours of Monday.

The International Olympic Committee said it had spoken to Tsimanouskaya and that she was being accompanied by a Tokyo 2020 staff member at the airport.

"She has told us she feels safe," the IOC said in a Twitter post.

It added the IOC and Tokyo 2020 would continue their conversations with Tsimanouskaya and the authorities "to determine the next steps in the upcoming days".
