Penn State University police and the FBI are investigating a potential threat posted to Twitter Wednesday that warned of a mass shooting at Beaver Stadium. 

The Daily Collegian reports that the account has since been deleted, however, a screenshot of the original tweet was shared by another Twitter user.

The tweet read: "I have decided that I'm going to commit the biggest mass shooting in history of the world, killing thousands of fans in beaver stadium during one of the games next year."

Penn State University Police and Public Safety said on its Facebook page  that the department and the FBI are working to determine its credibility.

"There is no immediate danger to the Penn State community,"  according to the post. "Penn State takes all threats very seriously and University Police and federal authorities are actively investigating. As always, University Police encourages everyone to always be vigilant. If you see something, say something."

Penn State is scheduled to open its season Saturday, Sept. 1, at home against Appalachian State.
