The University of Missouri (UM) police arrested a 19-year-old non-student for making a "terrorist threat" by promising violence against black people on campus.

Law enforcement was alerted on Tuesday night to a message on YikYak, a social media platform where users can post anonymously. The suspect, Hunter Park, allegedly threatened to "shoot every black person" he saw on Wednesday, Reuters reported.

MUPD apprehended Park Wednesday morning, the school confirmed in an alert posted to its website. After being taken into police custody, he was held on $4,500 bond.

#PrayforMizzou began trending on Twitter Tuesday night and Wednesday morning, as students and people around campus detailed potentially dangerous demonstrations.

However, there have been false reports, particularly from MU's student body president, Payton Head. He posted on his Facebook account that the KKK was "confirmed" to be on campus, but later stated he found out that was not true. He apologized and said he mistakenly relayed false information.

Last Monday, an MU graduate student named Jonathan Butler began a hunger strike and vowed not to eat until the school system's president, Tim Wolfe, resigned. Butler and a student group called Concerned Student 1950 were protesting the Wolfe administration's response to various issues on campus, particularly those concerning racial tension.

Butler's hunger strike lasted nearly a week before the UM football team's black players announced on Saturday they would not play any football until he ate again. The next day, the rest of the team and its head coach, Gary Pinkel, proclaimed they too would not take part in football activities until Butler ended his strike.

On Monday, Wolfe resigned and UM Chancellor R. Bowen Loftin announced he would step down and transition to a new position, the school announced in a statement. Since, the school's Columbia, Mo. campus has been embroiled with racial tension.
