Russian police will use a lie detector when questioning witnesses as they investigate an acid attack on the Bolshoi Theater’s artistic director, Sergei Filin.
Several people will undergo polygraph tests, a spokesman for the Moscow police said by phone today. Investigators spoke last week with the Bolshoi ballet’s principal dancer, Nikolai Tsiskaridze, as well as other employees of the theater and Filin’s relatives and acquaintances.
