According to Memorial reports, there is a system of "conveyor of violence" in Chechen Republic, as well as in neighbouring Ingushetiya. People are suspected in crimes connected with activity of separatists squads, are unlawfully detained by members of security agencies, and then disappear. After a while some detainees are found in preliminary detention centers, while some allegedly disappear forever, and some are tortured to confess to a crime or/and to slander somebody else. Psychological pressure is also in use. Known Russian journalist Anna Politkovskaya compared this system with Gulag and claimed the number of several hundred cases.
