That's “E”!

It is clear now who makes the list of unreliable persons. The history about “the lists of unreliable persons” in which there is supposed to be some opposition figures, who have regularly interested the police (that’s that “Novaya Gazeta” wrote about), has finally ended.

Central Internal Affairs Directorate of St. Petersburg and Leningrad region has not only admitted that the lists really exist, but also pointed out the source of information which helped to make the lists.
The source is expected – well-known Department of Counteraction to Extremism or just “E”- department.
