However, she refused to board the flight and sought protection from Japanese police before later gaining asylum in Poland. read more Athletics head coach Yuri Moisevich and team official Artur Shumak were then kicked out of the Games by the International Olympic Committee (IOC), days after they ordered Tsimanouskaya to pack her bags and go to the airport. read more The 24-year-old Tsimanouskaya had said she did not feel safe about returning to Belarus, which has been gripped by a sweeping crackdown on anti-government dissent following mass protests that erupted last year over a disputed election.
