(CNN) A leading Russian scientist in hypersonic flight was arrested on suspicion of treason on Friday, according to Russian state media.
Dr Alexander Shiplyuk, director of the Institute of Theoretical and Applied Mechanics of the Russian Academy of Sciences' Siberian Branch, is the third Russian scientist this summer to be arrested on suspicion of treason.
The institute's scientific director Vasily Fomin told the Russian news agency TASS that Shiplyuk was sent to the Lefortovo pre-trial detention center in Moscow.
