In the days following the resignation of Tim Wolfe, president of the University of Missouri system, the climate on the University of Missouri-Columbia (Mizzou) campus became noticeably tense. For many students of color, it still feels unsafe.

Late Tuesday (Nov. 10) reports emerged of anonymous threats against students of color on campus, via the popular anonymous posting app Yik Yak, that Raw Story reports read "I’m going to stand my ground tomorrow and shoot every black person I see.”

Early Wednesday (Nov. 11) morning, university police announced they had made an arrest.

Nineteen-year-old Hunter Park, who is not a University of Missouri- Columbia student, was arrested just before 2:00 a.m. Wednesday "for making a terrorist threat" and was brought to a local county jail, police said.

Despite the arrest, some Mizzou students said on Twitter that they still do not feel safe, and that their fears were not being taken seriously by various faculty and administrators. Late Tuesday night, the student government sent an email requesting that Wednesday's classes be cancelled, ending their concerned note with a desperate "please, please, please, please."

While classes remained in session, the university did send out words of support to their students via Twitter early Wednesday afternoon:

Yik Yak's creator also responded to the threats in a blog post on Wednesday, condemning those who use the app like that:

It’s our hope that the range of discussion on MU’s campus can help to bring about positive resolution and a better understanding within the community. But there’s a point where discussion can go too far – and the threats that were posted on Yik Yak last night were both upsetting and completely unacceptable. Let’s not waste any words here: This sort of misbehavior is NOT what Yik Yak is to be used for. Period. It is not condoned by Yik Yak, and it violates our Terms of Service.

A representative from Yik Yak also told MTV News that "Yik Yak cooperates with law enforcement and works alongside local authorities to help with investigations. We may provide information without a subpoena, warrant or court order when a post poses a risk of imminent harm."

MTV has reached out to the University of Missouri for comment.
