CHICAGO (AP) — The latest on the aftermath of the shooting of a black teenager by a white Chicago police officer and an online threat that prompted the University of Chicago to cancel classes for a day (all times local):

10:20 a.m.

Classes have resumed at the University of Chicago's Hyde Park campus.

University spokesman Jeremy Manier said Tuesday morning that operations were back to normal. The university closed the school on Chicago's South Side and canceled classes Monday after receiving an online threat that 16 white men on campus would be killed.

Previously, the university said there would be additional security through the remainder of the autumn quarter. Winter break starts Dec. 12.

A 21-year-old University of Illinois at Chicago student, Jabari Dean, was charged with making the threat and is scheduled to appear Tuesday in Chicago federal court.

Dean made the threat in retaliation for the fatal shooting of a black teenager by a white Chicago police officer. The officer has been charged with first-degree murder.

Chicago Mayor Rahm Emanuel's office says he will create a Task Force on Police Accountability.

Emanuel will hold a news conference Tuesday morning to announce the new effort. His office says the task force will review the Chicago Police Department's current systems for accountability, oversight and training.

A mayoral spokeswoman didn't immediately respond to an email asking if the move comes in response to a rash of protests following the release of a video showing a white police officer shooting black 17-year-old Laquan McDonald 16 times.

The panel will include victims' rights representatives, law enforcement organizations, young people and elected leaders. The panel's recommendations will be presented to Emanuel and the Chicago City Council by March 31.

The University of Chicago is set to reopen a day after a 21-year-old man was charged with making an online threat that 16 white men on campus would be killed.

The posting suggested the killings would be in retaliation for the fatal shooting of a black teenager by a white Chicago police officer.

The campus is set to reopen Tuesday.

Security experts say the university may have felt it had no choice to shut down for a day.

The city has been on tenterhooks amid protests that followed last week's release of video showing the officer shooting the teen 16 times. Michael Fagel teaches emergency management at several universities, including in Illinois. He says that may have helped force the university's hand.
