I am a teaching assistant and master's student in the math dept. at a large state university. I was holding a discussion section this morning when some young man walks in with his shirt off acting verbally belligerent. He comes up to the front of the room and just kind of stands there, not saying anything just kind of smiling in this creepy way and showing absolutely no signs of embarrassment or anything. After asking the class if anyone knew him (no one did), I told him he could either leave right now or I would get someone to remove him. I'm a small guy and he wasn't huge but he was certainly bigger than me.
He didn't leave so I stepped out of the room to get someone, although in retrospect I had no idea at the time who I would have gotten, but then as soon as I stepped out I realized that that probably wasn't a good idea since he could take my stuff or who knows what. So I walked back in and sure enough he's got my water bottle in his hand, so I grab it from him and say something to the effect of,
!@#$ it, does anyone big want to help me get this guy out of class?
And two guys stand up, and one of them is clearly super pissed at this guy disrupting class and goes straight over to the guy and BAM hits him in the face super hard and he goes down and then hits him again and then kicks him in the face all in the span of like 5 or 6 seconds, like a proper #$!%ing beat down, and there are girls screaming and I'm a bit in shock as I was expecting him to just kind of strong arm him out of the class, and one girl comes up and is like
stop hitting him stop hitting him!
I don't exactly remember what happened next, but the guy must have left and then the assistant dean appeared almost immediately. I talked to her privately and explained quickly what happened, but I didn't say that the student hit the guy, I just said he got him out of class. She said I would need to file a report. I then held class as usual, and everything was fine.
I tried to talk to the student privately after class, but the assistant dean came back in. I asked the assistant dean if she could step outside while I talked to the student in private, since I didn't want to incriminate him. But she got super offended and told me that "I shoo you, you don't shoo me, get this straight I'm your superior." So I apologized, but I think maybe the look on my face wasn't sufficiently contrite, I was really taken aback. So she writes down my name.
No one -- not my professor/student-teacher liaison, not my ombudsman -- seems to know what I should expect from all this. I also really don't want the student to get into trouble, since I did ask for help removing the guy. I scheduled a meeting with the dean, and now I'm super worried that I'm going to be fired or kicked out of my masters program. What should I expect from all this?
Update: I found out that the guy who was disrupting class got arrested later that day and he was not a student. I also talked to several students who said that this is not the first time he has done this, and that several weeks ago in another class he walked in and lit a cigarette, and the professor took the cigarette out of his mouth, stomped on it, and then physically threw him out of class.
