At about 6:30 p.m., 3-4 officers on foot saw the man "exhibiting characteristics of an armed person" and went to question him, according to tweet by CPD spokesman Anthony Guglielmi. A confrontation then ensued and the man was shot, he said. A weapon was recovered at the scene, Guglielmi said.

The incident occurred near 71st Street and Clyde on the South Side, where crowds gathered afterwards and, at times, scuffled with police. The crowd chanted, "No justice, no peace." After hours of tension, the group became "combative" and arrests were made after protesters jumped on top of two squad cars and causing damage.

During a Saturday night press conference, Fred Waller, CPD chief of patrol, said the man was swinging his hands and trying to make an escape when it appeared that he reached for his gun. When asked if the man had fired his weapon, he said: "not that I know of."
Witnesses said the man was shot several times. The victim was pronounced dead at Jackson Park Hospital, fire officials said.
Witness Allen Davis said that police saw the man's holster and asked him for his concealed carry permit, but when he reached for it, police shot him.
No officers were hurt, police said.
