The latest about an online threat that led the University of Chicago to cancel classes on Monday (all times local):

3:10 p.m.

A 21-year-old Chicago resident is charged with transmitting a threat in interstate commerce.

A federal criminal complaint said that Jabari R. Dean threatened on a social media website to kill 16 white male students or staff at the University of Chicago.

The threat came days after a video was released showing Officer Jason Van Dyke shooting 17-year-old Laquan McDonald 16 times. It prompted several days of protests in the city.

The complaint says an FBI officer wasn't able to see threat that was posted on Nov. 28, but reviewed a screenshot of it provided by the person who reported the threat.

Authorities said Dean posted online that he would "execute approximately ... 16 white male students and or staff, which is the same number of time (sic) McDonald was killed."

The complaint also said Dean admitted to FBI agents that he posted the threat and took it down shortly after.

Federal authorities say an online threat against the University of Chicago appears to have been motivated by the 2014 Chicago police shooting of a black teenager of which a video was released last week.

A criminal complaint released by the U.S. attorney's office in Chicago said Monday that 21-year-old Jabari R. Dean of Chicago, threatened online to kill 16 white male students or staff at the University of Chicago.

A video released last week of Officer Jason Van Dyke shooting 17-year-old Laquan McDonald 16 times prompted several days of protests in the city.

Authorities said Dean posted that he "execute approximately ... 16 white male students and or staff, which is the same number of time (sic) McDonald was killed."

UIC said in a separate statement Monday that it was one of its students living off-campus who was arrested.

Dean is due to make an initial appearance in federal court at 3 p.m. Monday.

Federal authorities say a suspect is in custody related to a threat at the University of Chicago that led to the school canceling all classes and activities scheduled for Monday on its main campus.

Joseph Fitzpatrick, a spokesman for the U.S. attorney's office in Chicago, says the individual is in federal custody and that charges are pending "in connection with the threat at the University of Chicago."

The normally bustling University of Chicago campus is largely quiet after it was shut down because of an online threat of gun violence.

Few students walked in the surrounding neighborhoods Monday morning, while Chicago Police Department squad cars and a wagon patrolled streets, along with campus security cars.

The school canceled all classes and activities following the threat, which was passed on by the FBI and mentioned the quad and 10 a.m. Monday. That time appeared to come and go without any incident.

Security staff in yellow jackets stood on campus walkways, including the quad.

The school urged faculty, students and non-essential staff to stay away on Monday from the Hyde Park campus on Chicago's South Side and told students in college housing to stay indoors.

Tyler Kissinger says as soon as people heard that the University of Chicago was shutting down because of an online threat of gun violence they closed their books, shut down laptops and hurried home.

Kissinger is the student body president. He was working at a campus coffee shop on Sunday night when the manager told him to start closing up and go home.

Kissinger says students haven't been given details about why the school was closed Sunday night and remained closed Monday.

The school canceled all classes and activities following the threat, which was passed on by the FBI and mentioned the quad and 10 a.m. Monday.

He called the threats a reminder that residents in the neighborhoods around the campus, which is on the South Side of Chicago, live with the threat of gun violence every day.

Kissinger says he only recalls the school being closed once before — because of weather.
