UPDATE 2:26 p.m.

Penn State Police have been alerted to an anonymous threat posted on the social media platform Yik Yak and are attempting to verify its credibility, according to a Penn State News release.

The threat was posted on the app at about 10:29 p.m. Saturday and indicated a possible shooting at the HUB-Robeson Center on Monday, according to the release.

Police were alerted to the threat today by students who had seen the post on the app, which allows anyone to post anonymously and sorts the posts by region, according to the release.

Penn State Police will be stationed at the HUB on Monday as a precaution, according to the release.

"University police are aware and have been investigating and monitoring social media since this morning," Penn State spokeswoman Lisa Powers said via email. "They are currently discussing best course of action. While the threat is anonymous and we cannot yet determine its credibility - all threats are taken seriously and police are working vigorously on determining its origin and its validity."

According to Yik Yak's legal guidelines, they may cooperate with police in the case of emergencies, including threats.

"Yik Yak may disclose user account information to law enforcement — without a subpoena, court order, or search warrant — in response to a valid emergency when we believe that doing so is necessary to prevent death or serious physical harm to someone (for instance, in cases involving kidnapping, bomb threats, school shootings or suicide threats)," the guideline reads. "Yik Yak evaluates emergency requests on a case-by-case basis."

While the posts are anonymous, Yik Yak does keep a log of IP addresses, GPS coordinates and time and date for each message posted on the platform, according to the guidelines.

The app — "an anonymous messaging app that allows users to create and view posts within a 10 mile radius" — does not have users provide real names, addresses, phone numbers, email addresses or other identifying information.

Police said they are continuing to investigate Monday's threat. If anyone has any information, police ask they call 814-863-1111, according to the release.
