In the original version of the investigation of the madness of the attacker, nobody believes. An eyewitness of the incident Julia Petersons is sure that it was not a flash of insanity. He came here for a day, walked through all the corridors, looked out, my girls saw him, she says..

"Radio Liberty" reports that at least ten people were detained on suspicion of involvement in the attack, two of them were charged with complicity in committing a terrorist act. Among those arrested are Arthur Hajiyev's acquaintances, who shared his views. Several interlocutors of the radio station from Muslim circles confirmed that the young man was a member of the community of radicals.

Among those arrested on suspicion of preparing for the terrorist attack - the natives of Dagestan Ilnar and Usman, who even in the mosque "prayed separately", "not behind the imam," says a correspondent of the radio station. Such people in the local Muslim community are considered extremists, they are notified about special services. After the video surveillance cameras were installed in the mosque, men who prayed separately stopped walking there.

Along with the extremists, obviously "left" people got into the field of view - for example, the 19-year-old native of Tajikistan, Naimjon Ikromov, once studied with Hajiyev, but did not communicate with him. Now Ikromov faced the threat of deportation.

According to his lawyer, the investigators apparently did not find anything serious about his client and decided to accuse him of hooliganism and deport him.

August 19, 19-year-old Artur Hajiyev attacked with an ax and a knife on passers-by, wounding seven people. He was shot by policemen. The next day after the incident, the terrorist organization "Islamic State" (banned in the IG) distributed a videotape of the oath of Hajiyev, recognizing him as a soldier of the Caliphate - in the video a certain young man swears to the terrorist leader Abu Bakr al-Baghdadi.
