This was reported by Interfax, referring to its source.
At the moment, there are no official comments on the detention of the former parliamentarian.
Local media indicate that the detention is related to criminal cases involving Natarov's son, ex-adviser to the head of the region, Anton Natarov.
It's worth reminding that Sergey Natarov himself was a State Duma deputy from the Krasnoyarsk Territory from the Liberal Democratic Party.
This year he won the elections to the regional Legislative Assembly.
Recall that in the middle of last month, a deputy of the Legislative Assembly of the Primorsky Territory Artyom Samsonov, suspected of a minor plant, was detained.
