There were a few scary minutes at Seattle University on Wednesday when an incoherent man trespassed on campus.
About 50 law students were in the midst of a lecture class when a strange man, wearing a trench coat and holding an ice cream cone opened the door and just walked right in.
The suspect circled the classroom, and began talking incoherently and turned over tables and other classroom furniture.
The professor was able to hit an emergency button, calling campus police. The SU security officers escorted him off campus and followed him down 10th Avenue and East Union Street until police arrived.
Seattle Police arrested the 38-year-old suspect for criminal trespassing. The police believe he may have issues with mental illness.
