The International Olympic Committee (IOC) said Tuesday that it is investigating the conditions under which Belarus allegedly tried to force sprinter Krystsina Tsymanouskaya to return to the country.
The 24-year-old on Sunday sought protection from police at Haneda Airport in Tokyo after, she said, team officials had removed her from Tokyo 2020 and transferred her to the airport.
She had earlier complained on social media that her coaches had instructed her to compete in an event she was not scheduled for, which she said was deemed as criticism of the Belarus government.
Tsymanouskaya has since been staying in a safe place and is waiting to travel to Poland, which has offered her a humanitarian visa, IOC spokesperson Mark Adams said.
"The IOC has decided to launch a formal investigation into the situation of the NOC of Belarus. It will be led by the IOC administration. We need to establish the full facts, we need to hear everyone involved," Adams said at a press conference in Tokyo on Tuesday.
