“It happened in the tram behind me. Suddenly there was commotion. The tram stopped in a bend so I could clearly see what was happening in the tram set behind me. The door of the tram was forced and windows were smashed. There was confusion in our tram set, but it remained fairly calm.”
“At that moment there was certainly already a shot in the tram behind me. You heard about the plop-plop-plop sounds, as if there was a muffler on it. Then I saw people running outside, really for their lives. I felt that he was focusing specifically on someone because I saw a woman crawling out. Bystanders tried to pull her away, but when they did, that man went after her specially and aimed at those bystanders.“
“I couldn’t see what he looked like. He was wearing a dark coat, a normal posture, and a long gun in his hand. Just such a hand gun, not an automatic weapon, as far as I could see. Then he went after someone with a yellow vest trying to help that woman, and after that I could not see it anymore.”
Update3: A new photo of the suspect, Gökmen Tanis, has been released:
