"The University was informed by FBI counterterrorism officials today (Sunday) that an unknown individual posted an online threat of gun violence against the University of Chicago…. Based on the FBI’s assessment of this threat and recent tragic events at other campuses across the country, we have decided…, to exercise caution by canceling all classes and activities on the Hyde Park campus through midnight on Monday," Robert J. Zimmer said in statement.
In the course of the day, the university will have an increased police and security presence on and around campus, according to the statement.
The University of Chicago Laboratory Schools, the University of Chicago Charter School campuses, the University libraries, the Quadrangle Club, and other campus facilities will also be closed on Monday.
Over the year, the United States has seen a growing number of mass shooting incidents, including three school shootings in October. In other cases, shooters have opened fire in churches, movie theaters, and military facilities.
