My friends and I were waiting at a small shop near the departure door because there were a lot of fans who sat on the floor so we couldn't get to the very front.
The fans started practice singing and all, so we followed along then a couple minutes later they all started getting up because soshi arrived from the right side and we all sang Complete. The girls looked happy they even sang when they were putting their belogings in the trays.
Then a fan said we can actually go down to the escalator where the girls will go through because there are no barricades or gates around it. So the fan suddenly became our friend and led us, we took a short cut through an exit door and came out at some stairs and through another door. Next thing we know, we are at the lower floor. There were quite a lof fans already there and as we get in the crowd, soshi were making their way down the escalator. My friend wanted to have a better look. We screamed Yuri! Yuri! and started moving forward because everyone was doing so. We were focusing on Yuri and then we heard a fan shout "HEY!!!" and then a girl screamed. We heard a loud bang llike on a metal bar or something. Then everyone started screaming "Jessica" and we could hear the managers and staff calling each other. The other Soshi members ran towards us but we were pushed aside by a male staff wearing blue. Between other fans we could see Jessica's body on the ground and she didn't move for a couple of seconds. Then Yuri, Yoona and Sunny came from behind me and started calling Jessica. Sooyoung was really shocked she kept putting her hands on her mouth. After Jessica was lifted up by one of the manager, Yoona and Yuri started crying but no one said anything.
We don't know where the person who pushed Jess because he was gone after the chaos. We saw Jess leaning towards theanager but she didn't even walk properly. After they were gone, we started asking people what happened and they said the security thought Jess was someone who was blocking the way..
They said some other things but in Chinese I can't understand.
