It was reported to the FBI, which contacted officials at the University of Chicago, prompting them to shut down campus out of an abundance of safety.

He has been identified as Jabari R. Dean, 21, of Chicago. Jon Seidel, the Chicago Sun-Times' Federal Courts Reporter, tweeted that Dean "posted the threat from his phone and said he took it down shortly after posting it."

The threat originally read:

"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."

In a statement, the University of Illinois-Chicago confirmed the arrest but said there were no threats made to the UIC campus.

No weapons were found in a search of the suspect's off-campus apartment on Monday morning.

The decision to cancel classes and activities at the University of Chicago's main campus was made late Sunday night; in the announcement, officials said they intend for classes to resume on Tuesday.

The arrest follows the release of dash cam footage of McDonald's death last week, which spurred protests throughout the holiday weekend in Chicago.
