A Chicago TV station has spoken with a law student inside the building, who said that about 50 students were inside for a first-year lecture when reports came in of an armed man spotted in an elevator on the building's 11th floor. The man appeared to be carrying a gun in his waistband, the story says.
That's pretty much all the news out there for now. Northwestern officials have told everyone in the building to lock themselves in their offices, and the student who communicated with media via his cell phone reported that people are laying low and staying away from doors and windows. The student said people were "calm" despite the situation.
