I bought a poster at flatstock, and I left the festival to go put it in my car for safe keeping. I was walking on the sidewalk, they opened the fence to let in a van or something.

The fence swung open like, 2 feet in front of me, so I stepped to the curb and kept walking a dude in a staff shirt stepped in front of me and said, "Everybody stop" or something similar at this point, we were like a foot apart so I kept walking and
he pushed me.

I stepped down with one foot on the street and I was past him at which point he grabbed me, forcibly and hard from behind by my hoodie and yanked and pulled me into the street.

My hoodie was unzipped if it was zipped I think he would have ripped it, and/or thrown me to the ground in the street
instead I just stumbled and regained my balance.

I was shocked to be grabbed at all, let alone in such a forceful way. I immediately threw my hands up in the air and screamed, "I am on a public sidewalk, you are not a law enforcement officer!" repeatedly.

One of the other staff people said, "Let him go!" and he did finally.

I spun around, still with my hands in the air, and I said, "What are you doing? I am on a public sidewalk!"

He had rage in his eyes and said, "You are/were in in the street impeding traffic." I said, "YOU are NOT a law enforcement officer!" And the only reason I was in the street was because that was the direction that I was forcibly throw by him.

He took two steps towards me, at which point other staff people stepped in and got him away
