The lawsuit says that in order to seize control of the enterprise, Tatevos Surinov, Ibrahim Suleimanov and Rifat Shaikhutdinov conspired with the head of the Federal Insolvency and Financial Recovery Service Georgy Tal.

In particular, Suleimanov is accused of the murders of Tal, with whom a conflict arose, the chairman of the trade union organization Vnukovo Airlines Borisov, as well as the attempted murder of lawyer Peregudov.^[1]
