CHICAGO (AP) — Federal authorities have decided not to prosecute a man whose online threats prompted the University of Chicago to close for a day last November.

University of Illinois at Chicago engineering student Jabari R. Dean threatened to kill whites at the University of Chicago after the release of video of the 2014 shooting of black teenager Laquan McDonald by a Chicago police officer.

Prosecutors on Wednesday told U.S. District Judge John Blakey they've agreed to defer prosecution of Dean on one count of transmitting a threat in interstate commerce. Dean must perform 100 hours of community service, pass drug screenings and comply with other conditions similar to pretrial bail restrictions.

Defense attorney Damon Cheronis says Dean hopes to finish his studies. He was kicked out of school because of the charges.
