Runner Kristina Timanovskaya is said to have voiced her dissatisfaction at being added to the 4 x 400m relay team after she reportedly claimed that three Belarusian athletes, named as Maria Zhodik, Anna Mikhailova and Kristina Mulyarchik, were unable to fly to Tokyo to compete because there were not enough doping tests available.
The Games debutant was subsequently taken to the airport by two officials to be flown back to Belarus in a state of fear, according to a heavily-followed Minsk reporter and numerous other accounts.
“It turns out that I have just learned the news that I will also run a third event at this Olympics – the relay race 4 x 400 meters," Timanovskaya said.
"It turns out that our 'very cool bosses' decided everything, as usual, for us. They messed up with the girls who do not have enough tests to fly to their first Olympics in their life... cool, guys. Well done."
Writing on Twitter on Sunday morning Belarusian time, journalist Hanna Liubakova said: "Apparently, representatives of the Belarusian national team took her to the airport. It looks like kidnapping.
"Tsimanovskaya was accompanied to the airport by two members of the Belarusian sports delegation. She is now with the police and volunteers. When asked if she was afraid to fly to Belarus, Tsimanouskaya answered, 'yes'."
A report from Belarus appeared to show Tsimanovskaya talking and reported that the Olympic Committee of Belarus had decided to end her campaign "due to her emotional and psychological state", which the athlete was said to have labeled a "lie" on Instagram while planning to seek asylum from the Austrian embassy.
