One of the company\'s leading male dancers Pavel Dmitrichenko, the suspected mastermind of the January attack, signed a written confession along with two other suspects who were all arrested on Tuesday. \"The motive of the crime was the hostile personal relationship Pavel Dmitrichenko had with Sergei Filin, which was linked to their work,\" police said in a statement.

The police said Dmitrichenko was the mastermind of the attack, accomplice Yury Zarutsky the assailant who flung acid into Filin\'s face and Andrei Lipatov the driver at the scene.
