Auburn University has canceled classes for today following what school officials are calling an unsubstantiated threat on campus.
A message posted on the university's website says authorities don't believe the threat is credible.
But the school says it suspended classes and other normal operations for a day because of anxiety among students and parents. Authorities also are increasing the police presence around campus.
The university says information is being circulated about a threatening message posted in a campus restroom.
Posts circulating on social media show what appears to be handwritten threat of a campus "rampage" today. A university alert went out after the posts began spreading.
Today is the seventh anniversary of the attack in which a student gunman killed 32 students and faculty at Virginia Tech University.
