A more detailed story, about the kneading at the entrance in Zelenye Gorki, according to the tenant:

Hello, about what happened at 3.00 a.m., they started knocking at my apartment, looking through the peephole, I saw this young guy who knocked on all apartments shouting what the addicts sprayed pepper gas.

I didn't open it right away, but then I saw a girl run away from the upper floors and then someone else, I thought that a fire had started on the upper floors and people were running downstairs, I went to the staircase, but there was no smell of smoke, but I felt a burning sensation in eyes, nose and mouth.

At that moment, this guy ran to the door, shouting that drug addicts sprayed pepper spray, and call the police, before closing the door he threw something into the apartment, I thought it was a phone and threw it back out the door and only then I noticed that it was pepper spray, at 3.22 I called the police (according to the video, it was at this moment that the guy attacked the girl.).

Since I opened the door, the gas got into the apartment and my wife and children began to choke at home (one of whom is 4 years old).
