Just one day after students discovered a handwritten bomb threat in Schroeder Hall at Illinois State University, school officials are now saying that nothing dangerous has been found and the campus is safe.

According to the Associated Press, school officials contacted the FBI as a precaution after the threatening note was discovered. Fall classes -- which are due to begin on Monday -- will proceed as scheduled, but security will remain heightened through the week.

ISU president Timothy J. Flanagan sent out a mass email to students, faculty and staff earlier today to give them an update on the situation. Read it in full below, via UPI:

“Dear Students, I am writing to give you a brief update on yesterday’s incident regarding the threatening note found in Schroeder Hall. University police and security personnel have conducted thorough building sweeps and are keeping a presence in Schroeder, something that will continue through Friday.

"Nothing suspicious has been discovered and the building remains safe and secure. Over the years, threatening notes of this type have appeared on several occasions, not only at Illinois State, but on college campuses across the country.

"While these notes are most often viewed as an attempt to disrupt normal activity, we must always take such communications seriously. We do not want to overreact to this situation and add credibility to the individuals and copycats who commit such acts.

"Still, your safety is our first priority, so I felt it necessary to take these extra safety precautions, alert you quickly and keep you updated. Although this incident did not rise to the level of requiring an emergency text alert, which occurs when there is an immediate safety danger, it serves as a reminder that we should be mindful of our environment and security.

"If you haven’t already done so, please sign up for our emergency texts alerts by following links from IllinoisState.edu/alerts. Information is also communicated via the University homepage, Facebook, Twitter feeds and other applications.

"Finally, I want to thank you for your patience and maturity throughout this incident. Your behavior is just one more reason we are proud of our Illinois State University students.”
