Huffington Post reports that the university released a statement to students that the online threat included a potential attack on Monday at 10 a.m on the campus quad by an unknown perpetrator.
"Based on the FBI's assessment of this threat and recent tragic events at other campuses across the country, we have decided in consultation with federal and local law enforcement officials, to exercise caution by canceling all classes and activities on the Hyde-Park campus through midnight on Monday," an email from University President Robert Zimmer.
Because the threat included a specific time and place, faculty and staff were advised to "remain indoors as much as possible if they are on campus" and to not come to campus at all.
On the return from the holiday vacation, the quad is a popular meeting place for students to gather. No word has been released as to future class cancellations or continued threats against the university campus.
