From the article:
NORTHFIELD, MINN. – A racist threat against a St. Olaf student that touched off campuswide protests and forced the college to cancel classes earlier this month was a hoax, the school revealed Wednesday.
A student confessed to writing the note, St. Olaf President David R. Anderson wrote in a message to students. The threat — an anonymous, typewritten note — was “fabricated,” he said, as an apparent “strategy to draw attention to concerns about the campus climate.”
