Leading soloist Svetlana Lunkina has taken leave from the world famous Bolshoi Ballet until the end of its current season and gone into hiding in North America.
The move follows a series of unspecified threats aimed at her husband, Vladislav Moskalyev, who is currently embroiled in a legal dispute with a former business partner.
Lunkina tells Russian newspaper Izvestia, ""I think we need to react to these threats. These people have no right to interfere in our private lives or my professional work. I was supposed to be doing a lot of interesting work, including several premieres.""
News of the mysterious threats comes less than two weeks after Sergei Filin, artistic director of the Bolshoi, was targeted by an unknown attacker in Moscow who threw sulphuric acid in his face.
Lunkina's case is not believed to be linked to the attack on Filin.
