Moscow police question suspect in Bolshoi acid attack

Police in Moscow have brought in for questioning a suspect in the acid attack on the Bolshoi Ballet's artistic director, Sergei Filin.

A brief report on the police website said the unnamed person was "one of the suspects" in the attack on 17 January, which shocked the arts world, BBC reports.

"The necessary investigative measures are now being taken," it added.
Mr Filin's eyesight was damaged when a masked attacker threw sulphuric acid in his face.
He was released from hospital in Moscow last month for follow-up treatment in Germany.
The attack came after a period of infighting at the Bolshoi, one of Russia's most prestigious ballet companies.
Russian commercial news website LifeNews quotes an unnamed source as saying the suspect is a man and was detained early on Tuesday. He is not connected to the Bolshoi, it says.

Searches were under way at the suspect's home and other addresses connected to him, it adds.
Mr Filin, 42, was badly burned during the attack, which happened in the street as he returned to his home in Moscow late at night.

A security camera apparently captured grainy footage of the event.
The artistic director said later he was certain who was behind the attack but would only speak after an announcement by investigators.

He argued the aim of the attack had been to remove him from his post, adding that he had long been the target of threats.
German doctors think they can restore some of Mr Filin's sight, the BBC's Daniel Sandford reports from Moscow.
A spokeswoman for the Bolshoi said they hoped he would return to the company for their trip to London this summer, our correspondent adds.
