Update (11/11/15): MSA president Payton Head deleted his Facebook post confirming KKK presence on campus and provided a new update:

I'm sorry about the misinformation that I have shared through social media. In a state of alarm, I was concerned for all... Posted by Payton Head on Tuesday, November 10, 2015

See original story from 11/10/15 below:

The resignation of University of Missouri system president Tim Wolfe and chancellor R. Bowen Loftin has been framed as a mere moment in the movement for equality for good reason. Those moves alone won't end the racism at Mizzou, as we're seeing clearly tonight. The campus has been home of several racist threats tonight, both IRL and on social media.

The Black Culture Center was placed under lockdown after a threat was called in Tuesday afternoon, ABC 17 reports. The threat came in during a meeting between Missouri Legislative Black Caucus and members of the group Concerned Student 1950, the major catalyst in the protests at Mizzou. This is the same site vandalized with cotton balls back in 2010.

The Maneater, Mizzou's student newspaper, has confirmed the Phi Mu sorority has been placed under lockdown after reports of the KKK being on campus. Payton Head, the student body president, has also confirmed the presence of the terrorist group, saying: "Students please take precaution. Stay away from the windows in residence halls. The KKK has been confirmed to be sighted on campus. I'm working with the MUPD, the state trooper and the National Guard."

A member of the track team also tweeted about a sighting:

Saw the KKK down greektown when I was getting my teammates.. It's real — Markesh Woodson (@KeeshyTooTrill) November 11, 2015

However, MUPD spokesman Brian Weimer told The Maneater, "There's absolutely nothing to indicate that (the KKK is on campus)."

A student took to Twitter to share her story of being threatened and harassed by a group of white people at Speaker's Circle (a Mizzou landmark) and in a blue truck without license plates. She expressed her fear numerous times, as well as hesitation to return back to the school tomorrow because of specific threats not to return.

Cody Mroczka, a reporter for Lake News online and a Mizzou alum, shared two videos from Speaker's Circle featuring a white man screaming profusely and mentioning the KKK. He says he received the clips from a close friend and grad student at Mizzou.

The social media platform Yik Yak was also home to several threats, both cryptic and specific, as captured on Twitter:

Another student reported sharing with his professor his natural trepidation at attending class tomorrow in wake of the racist threats. The professor doesn't seem to share (or understand) the concerns.

Chancellor Loftin, who will remain in his role until Jan. 1, says MUPD is aware of the threats and has increased security. The MU Alert system issued a similar statement:
