First of all, here's what happened, via MSU's student newspaper, The State News:
Students took to social media during an incident where a professor began yelling and reportedly stripped naked Monday afternoon at the Engineering Building. At 1:07 p.m., a call was received by the Ingham County Dispatch Center regarding a man screaming and yelling at the building, MSU police Sgt. Florene McGlothian-Taylor said. Police arrived on the scene shortly thereafter, took the man into protected custody and transported him to a local hospital. No students were harmed, and the man has not yet been charged for any crime.
Background story: I was in Calc 1 at Michigan State University, and my teacher was always pretty eccentric, but today he went overboard. Half way through class he started screaming at us, swearing left and right. He then started slamming his hands on the window and pressing his face against it, still screaming. Eventually he walked out and down the hallway to the end, all while screaming. He then came back into the classroom and took off his clothes, except for his socks. You know someones crazy when they leave their socks on lmao. At this point everyone in class ran out. We were literally scared for our lives. The police took about 15 minutes to get here, and during this time he continued walking around screaming.
More details, via another Redditor:
He was ranting about computers, Steve Jobs(pronounced Jobes), and how everything is just an act. He ran into the hallway and pressed his face up against the windows to the room and said something about him not yelling. Then he ran back in and started crying and pulled a dollar out of his wallet for some reason. At this point we all knew he had completely lost it.
Another eyewitness via HyperVocal:
I was in the classroom just down the hall(the classroom he is leaning on in the picture). We heard laughing from down the hall it quickly turned to yelling and cursing something about god. Next thing we knew his shirt was gone. Luckily from our vantage point we couldn’t see his lower half. Class was disrupted as we waited for the police to arrive. Took them 15-20 minutes even though the department is right across the street
