Two Belarusian coaches have been stripped of their Tokyo Olympics accreditations over an alleged attempt to force a sprinter to fly home, an incident that drew international condemnation.

The International Olympic Committee (IOC) on Friday said it had removed the accreditations of Artur Shimak and Yury Maisevich and they had left the Olympic Village.

IOC president Thomas Bach said at a press conference in Tokyo that the matter was "in the hands of the Disciplinary Commission but the procedure continues with the cancellation of the two accreditations and the disciplinary procedure is not over".

The Olympic body said this week it was investigating the pair over their role in the case of Krystsina Tsimanouskaya, who sought protection at a Tokyo airport to avoid being forced onto a plane home.

She said she feared for her life if she returned to Belarus, which has been wracked by political upheaval and a crackdown on dissent after disputed elections that returned strongman Alexander Lukashenko to power last year.

Tsimanouskaya was among the many Belarusian sports figures who in August 2020 had publicly criticised the violence against protesters at demonstrations that gripped ex-Soviet Belarus after the presidential vote.

But her trouble in Tokyo came after she posted on her Instagram, criticising her coaches for entering her into a race without informing her first.

The IOC said the two coaches "will be offered an opportunity to be heard" but said it had acted "in the interest of the wellbeing of the athletes" from Belarus who are still in Tokyo.

Tsimanouskaya, 24, arrived in Warsaw on Wednesday after being granted a humanitarian visa, saying she was "happy to be in safety".

Bach said the IOC had also offered her assistance to continue her athletics career in Poland.

"We've been in contact with Krystsina Tsimanouskaya from the very beginning of the case," he said. "We are very happy that she is safely in Poland and we have through the Polish National Olympic Committee also offered assistance... to support her in her sporting ambitions."

The row blew up after Tsimanouskaya, who competed in the 100m heats in Tokyo and was to have run the 200m, complained about being entered into the 4x400m relay without being consulted.

She said she was "surprised that the situation became such a political scandal because it started out as a sporting issue", adding that "she was "not thinking about political asylum" in EU member Poland.

"I just want to pursue my sporting career," Tsimanouskaya said.

The alleged attempt to return Tsimanouskaya to Belarus has prompted condemnation, with US Secretary of State Antony Blinken accusing Minsk of "another act of transnational repression".

In power since 1994, Lukashenko sparked international outrage in May by dispatching a fighter jet to intercept a Ryanair plane flying from Greece to Lithuania to arrest a dissident on board.

Belarus has also been in the crosshairs of the IOC since last year. Lukashenko and his son Viktor have been banned from Olympic events over the targeting of athletes for their political views.

Shortly before the Tokyo Games, Lukashenko warned sports officials and athletes that he expected results in Japan. "If you come back with nothing, it's better for you not to come back at all," he said.

The Olympic saga came as police in Ukraine said missing Belarusian activist Vitaly Shishov, whose NGO helps his compatriots flee the country, had been found hanged in a park in Kiev.

Police said they had opened a murder probe and would pursue all leads including "murder disguised as suicide", while activists accused authorities of "an operation... to liquidate a Belarusian who presented a true danger to the regime".

On arrival in Warsaw, Tsimanouskaya urged her fellow "Belarusians to stop being afraid and to speak out if they feel some pressure".
