COLUMBIA, MO - A day after protests brought down two University of Missouri officials, reports of racially charged threats permeated social media -- as well as a rumor the Ku Klux Klan had arrived on campus.
University police said they investigated and determined the reports Tuesday night were false. But the rumors had already spread far and wide.
"I'm going to stand my ground tomorrow and shoot every black person I see," a widely shared Yik Yak post said.
Another post contained a veiled threat.
"Some of you are alright. Don't go to campus tomorrow," the post said.
Yik Yak is a social media app that allows users to share anonymous messages, or Yaks, with others in a five-mile radius. However, the man police say they arrested early Wednesday for posting threats on Yik Yak and other social media -- Hunter M. Park, 19 -- was "contacted" in Rolla, more than 90 miles south of Columbia.
Park, who is from Lake St. Louis and is not a Mizzou student, was transferred to the campus police department, charged with making a terrorist threat and transferred to Boone County Jail where he was held on a $4,500 bond, police said.
University of Missouri Science and Technology posted this statement to their website:
“Threats of violence of any kind are not tolerated,” says Missouri S&T Chancellor Cheryl B. Schrader. “As a campus, we are grateful that this situation did not escalate. I thank both of the police departments for their swift action in handling this case. As always, the safety of our students, faculty and staff is our utmost concern.”
Tuesday evening MUPD was made aware of threats made on the anonymous social media platform YikYak and other social media sites. During its investigation, MUPD was able to trace the social media postings to Park. MUPD contacted Missouri S&T police for assistance with an arrest. At approximately 1:50 a.m., Park was arrested at Thomas Jefferson Residence Hall in Rolla for making terroristic threats. No weapons were found during the investigation. Park was transported to the Boone County Jail in Columbia, Missouri.
One of the app's developers, Brooks Buffington, told CNNMoney earlier this year that while federal law prohibited the sharing of personal information, "in cases of imminent threat or harm or something like that, we work with law enforcement to do what we can."
Even before the arrest was announced, campus police had insisted there was no imminent danger.
"Students need to be aware of what is going on, but right now there is no active threat on campus," police spokesman Maj. Brian Weimer said.
"The campus is not on lockdown. There is heightened awareness due to the national attention we are getting, but again the reports you are seeing on social media are largely inaccurate."
Police: No proof the KKK is on campus
Weimer said officers went to where the KKK was reported to be -- and found nothing.
"We have found no evidence of anything related to the KKK on campus," he said.
Student Body President Payton Head had already posted about it on Facebook.
"Students please take precaution. Stay away from the windows in residence halls. The KKK has been confirmed to be sighted on campus," Head wrote in a post that has since been deleted. "I'm working with the MUPD, the state trooper and the National Guard."
The police spokesman said the National Guard was not on campus, "nor have they been called to assist."
Head quickly apologized for spreading the rumor.
"I'm sorry about the misinformation that I have shared through social media," he posted on Facebook.
"I received and shared information from multiple incorrect sources, which I deeply regret. The last thing needed is to incite more fear in the hearts of our community."
University officials toppled
African-American students at Missouri have long complained of an inadequate response by university leaders in dealing with racism on the overwhelmingly white Columbia campus.
Protesters clamored for change and for university system president Tim Wolfe to step down.
Former Mizzou wide receiver L'Damian Washington said he believes Wolfe took "a lackadaisical approach to get things fixed. ... I think (he) just turned a blind eye to it."
The protests got two major jolts when student leader Jonathan Butler launched a hunger strike and the Missouri Tigers football team said it would not play until Wolfe stepped down.
The pressure worked. Wolfe resigned Monday, followed hours later by Chancellor R. Bowen Loftin.
Students, faculty and staff converged on the Carnahan Quad after Wolfe's announcement. They linked arms and swayed side to side, singing, "We Shall Overcome."
Marshall Allen, a member of the protest group Concerned Student 1950, said the change is just starting.
"This is just a beginning in dismantling systems of oppression in higher education, specifically the UM system," Allen said.
Media professor apologizes
During the height of the protests this week, professor and demonstrator Melissa Click was filmed grabbing a journalist's video camera, telling him he had no right to be there. She then asked for "muscle" to have him removed from the scene.
Click, to many people's surprise, was a professor of mass media.
After video of her outburst spread across social media, Click publicly apologized.
She also resigned her courtesy appointment with the journalism school, said the school's dean, David Kurpius.
That doesn't mean Click is out of a job. She is still an assistant professor at the communication school, but the courtesy appointment gave her the ability to work with journalism doctoral students in topics that fall into her area of research, Kurpius said.
How we got here
Protesters say racism at Mizzou -- sometimes blatant, sometimes subtle -- has simmered on campus for decades.
In 2010, white students scattered cotton balls outside the Black Culture Center.
In September, Head -- the student body president -- vented on Facebook about bigotry and anti-homosexual and anti-transgender attitudes after people riding in the back of a pickup truck screamed racial slurs at him.
In October, someone used feces to draw a swastika on the wall of a residence hall.
Even on Tuesday night, some reported incidents of threat or intimidation on campus.
"Im shaking and crying these white guys are in a monster blue pick up truck no license plate circling our car we almost couldnt get out," one student tweeted.
Washington, the former football player, said it may be hard for a white person to understand.
"Only a minority knows what it feels like to be a minority on campus," he said.
The University of Missouri's Columbia campus has a population of 35,000 students. The undergraduate student body is about 79% white, and 8% African-American. The school's faculty is also more than 70% white, with black representation of just over 3%, according to the university.
