MOSCOW, November 20 (RAPSI) - Former top Bolshoi Ballet dancer Nikolai Tsiskaridze will give testimony before Moscow's Meschansky District Court on November 25 in connection with an acid attack that left Bolshoi Artistic Director Sergei Filin with third degree burns to his face and eyes, RAPSI reported from the courtroom on Wednesday.

Filin suffered third-degree burns to his face and eyes on January 17 when unknown assailants attacked him with what is believed to have been concentrated acid. Shortly after the attack, a Bolshoi Theater spokesperson confirmed that Filin had received various threats.

Three men were arrested in March in connection with the attack, including Pavel Dmitrichenko, a leading Bolshoi soloist, the alleged attacker Yury Zarutsky and driver Andrei Lipatov. They each face 12 years in prison if convicted.

Filin returned to Moscow last September after six months of treatment in a German hospital. He has undergone more than 20 eye surgeries, and German doctors said that Filins eyesight had improved significantly. After losing over 90 percent of his vision in his left eye and becoming totally blind in his right eye, 80 percent of the vision in his left eye has been restored, and he can distinguish big objects with his right eye.

Filin suggested that the aim of the attack may have been to remove him from his position as artistic director and to destroy the prestigious Moscow ballet company's reputation.
