They had taken out a young lad a few minutes before. He left quietly it seemed, then they may have gone to eject this other guy and had a completely different reaction.
I didn’t see the female steward getting hit but it probably explains why a male steward was full on trying to exchange punches with fans. To the extent of moving back up the stairs to do it and having to be pulled back. I was really surprised by this at the time because it was escalating the situation. If the lady steward who was hit was the one I could see, she genuinely seemed to be trying to deescalate it all. It was dangerous to be near because the stewards and the fan struggled slowly all the way down the steps, where there was only a narrow space between the ends of the rows of seats and the concrete staircase. They were being pursued by fans and consequently fell into people in the seats behind them, with no way of knowing if they were potentially falling on a child or an older person etc. There was no space for us to move back. At one point a steward took a pretty dangerous looking fall over the top of the covered up rows of seats at the front. Stuff was also being thrown - something hit me in the face. Maybe a rolled up hot dog wrapper? It didn’t do any damage but it was thrown with force by one city fan and it hit another, me. It won’t stop me going away but it was unnerving.
