This also caught my attention from Ismene Brown's blog linked above
The company manager Ruslan Pronin is also reported to have surprised the troupe by announcing that Filin yesterday had a phone conversation with another Bolshoi dancer, Batyr Annadurdyev, which has resulted in him being asked to make a statement to investigators.
I do hope eventually it all comes to light, but it seems a shadow will be hanging over the Bolshoi for a while yet.
It may be more than that. According to this link, the conversation between the two was extremely unpleasant and as a result Annadurdyev submitted his resignation.
