Three men detained for the acid attack on the artistic director of the Bolshoi Ballet will face a judge Thursday.
The court will decide whether the three will remain in detention, go under house arrest, or be released on bail.
Among those detained is lead dancer Pavel Dmitrichenko who police say masterminded the attack on January 17.
The other two are: Yuri Zarutsky, who allegedly flung the sulphuric acid on director Sergei Filin, and Andrey Lipatov, who allegedly drove the getaway car.
If convicted, the attackers could face up to eight years in jail for willfully inflicting damage on the health of another.
