RIA Novosti reports about this.

“People had a very good idea at what moment this should happen, so that the audience from the audience could not move towards any other emergency exits and everyone would rush towards the stage,” Pomorin said.

At the same time, the cameraman noted that he himself was behind the scenes and knew about what was happening in the hall from the words of his film crew.

“My camera guys were standing there, I knew where everyone was, and the first ones said... something was wrong,” the man said.

According to him, the film crew was wearing headsets and this helped them escape: Pomorin gave the command to leave the equipment and leave the concert hall. 

Earlier, the FSB stated that the weapons of the terrorists who attacked Crocus were prepared in advance in a cache.

It was also reported that the attackers in Crocus were armed with AKs and had a large amount of ammunition.
