There are Defense Ministry troops, OMON and intelligence officers in this regiment. We were taken there. First we were interrogated and beaten. I was kicked and beaten with kalashnikov butts. It is cold in such pits, you cannot sit on the ground - the right way to catch cold.
People have to squat there.
First, I spend a day in a zindan. There were also two other people. They said they had been sitting there for three days already. They were taken for interrogation, never to come back. Later I found out that their relatives ransomed them.
