Former security service chief Oleksandr Turchynov said he didn’t order the destruction of a case file on reputed mobster Semyon Mogilevich.Two former heads of the Security Service of Ukraine offered vastly different accounts this week of the alleged role of Semyon Mogilevich in the lucrative gas trade between Ukraine, Russia and other former Soviet states, as well as the contents and fate of secret agency files about the alleged mobster.

Valentyn Nalyvaichenko, who headed the spy agency from 2006 to 2010, told the Kyiv Post in an interview that documents connecting Mogilevich with the nation’s gas trade had been destroyed by one of his predecessors, Oleksandr Turchynov, in 2005.
