EAST LANSING (WKZO) -- A professor at Michigan State University is in protective custody at a hospital after he stripped down naked in his class and began screaming.

MSU police went to the school's engineering building Monday upon reports of a man screaming.  The "State News," the university's student newspaper, reports the professor was shouting about "how no one can do anything right."

No one was injured.  The unidentified professor is not being charged with a crime.
