Bolshoi Ballet star Pavel Dmitrichenko has alleged he was attacked by three prison guards following a court hearing last week (ends20Oct13).

The dancer is due to go on trial in Moscow on Tuesday (22Oct13) on charges of masterminding an assault on Bolshoi boss Sergei Filin, who was left partially blind when acid was thrown in his face in January (13).

Dmitrichenko was in court on Thursday (17Oct13) for a pre-trial hearing, and his lawyer Sergei Kadyrov has alleged three prison officials assaulted him following the case.

Kadyrov claims a jail doctor noted the injuries his client suffered, and he is calling on authorities to launch an investigation into the incident.

He says, "I will appeal to the pre-trial detention's administration, as well as the Investigative Committee. A criminal case against the guards has to be initiated. No one should be allowed to beat a man down while he is handcuffed."

Dmitrichenko is due on trial at Moscow's Meshchansky District Court on Tuesday. It is alleged he colluded with two accomplices to attack Filin following artistic differences within the company.
