The University of Illinois at Chicago said Monday that one of its students has been arrested following an investigation into a threat made against the University of Chicago.
The threat had led to the closure of the University of Chicago campus Monday.
"We are monitoring this situation closely and are concerned about the impact this has had on our campus and the University of Chicago," Michael Amiridis, chancellor of the University of Illinois at Chicago, said in a statement.
According to the Chicago Tribune, the threat was made online to kill 16 white male students or staff at U of C in retaliation for the shooting of Laquan McDonald by a Chicago police officer.
"This is my only warning. At 10AM Monday morning, I'm going to the campus quad of the University of Chicago. I will be armed with an M-4 carbine and two desert eagles, all fully loaded. I will execute approximately 16 white male students and or staff, which is the same number of time McDonald was killed," wrote the commenter, who posted with the initials "JRD" and a Chicago Bulls logo, according to the police report. "I will then die killing any number of white policeman in the process. This is not a joke. I am to do my part and rid the world of white devils. I expect you do the same."
The cancellation of classes and activities hasd affected more than 30,000 people, including undergraduate and graduate students, faculty and staff, according to the University of Chicago.
The individual in custody has not yet been publicly identified.
