FROSTBURG, Md. (WUSA9) -- Police at Frostburg State University are investigating an anonymous, vague shooting threat made on an app.

A posting on the anonymous, location-based message app known as Yik Yak stated "At 5:30 tomorrow, I'm going to start shooting."

Based on the timing of the post, school officials say police believe that "tomorrow" refers to Wednesday, April 30.

Classes have not been cancelled at the school, but officials say students can use their personal judgement if they feel their personal safety is as risk. School officials say they alerted the campus out of an abundance of caution.

The following messages were posted on the university's website:

Message from President Gibralter:

I want to issue a clarification in response to questions from parents, students and others regarding the message about the anonymous, vague threat about which police have learned. Police must evaluate the credibility of threats on a regular basis. Our police agency and those agencies working in cooperation with us give this particular threat little credibility. This is for a variety of reasons, including that it was not declared to be specific to FSU. However, we decided that it was still important for the campus community to be aware and forewarned.

For those of you not familiar with this app, this article explains some of its features and what makes it unusual and troublesome.

This story details some of the issues Yik Yak posts have created elsewhere:

In consultation with the Provost and SGA president, we offer the following message: While we do not want to allow our campus to be held hostage to anonymous, vague threats, if you feel your personal safety is at risk, you are encouraged to exercise your personal judgment about whether or not to stay on campus for the remainder of the day.

Jonathan Gibralter, President Frostburg State University
