Alexander Bastrykin requested a report on the investigation into the death of Sergei Susdov.
The investigation committee clarified that earlier, in a program on the federal television channel, the circumstances of the death of a music critic in the city of Naryongri were discussed.
"The participants in the program doubt the conclusions of the investigation and draw attention to the contradiction between the previously announced version and the video recording of the events and other facts. Also, they insist on the need for further investigation into his death, including possible additional tests," the department said.
The investigative bodies of the Russian Investigative Committee for the Republic of Sakha (Yakutia) are investigating a criminal case regarding Susedov's death.
