The 24-year-old Russian citizen was flying with her boyfriend Roman Protasevich, a dissident blogger critical of Belarusian leader Alexander Lukashenko, on a Ryanair flight from Athens, Greece, to Vilnius, Lithuania, in May 2021 when it was diverted to Minsk by Belarusian authorities.
Belarus said at the time it had ordered the plane to land after an anonymous tip-off that there was a bomb on board.
The bomb threat turned out to be false, and Protasevich and Sapega were immediately arrested.
The diversion of a commercial flight to arrest the pair prompted international outrage and urged the European Union and United States to impose more sanctions against Belarus.
