Leonid Volkov, the ally, released the details on the Telegram messaging app and promised more details later on Monday.

Police detained more than 3,000 people and used force to break up rallies across Russia on Saturday after tens of thousands of people ignored the extreme cold and police warnings to publicly call for Navalny's release.
