"Officers that were responding got into a confrontation with this armed individual. The officers were forced to discharge their weapon, striking the individual," Chicago Deputy Police Chief Al Nagode said in an evening news conference. He said the man was visibily armed.

Responding officers reportedly fired six to seven shots at the suspect.

The man was transported to Stroger Hospital, where he was pronounced dead. A "semi auto handgun" was recovered, according to a tweet from Chicago Police's chief communications officer Anthony Guglielmi.

Both officers involved in the shooting will be placed on "routine administrative duties" for 30 days.

When officers arrived, the suspect allegely shot at them and barricaded himself inside an apartment complex stairwell, according to the Chicago Tribune.

He reportedly yelled obscenities at police and threatened to shoot if they approached him. He led police in a four-hour standoff before he was fatally shot by an officer at around 2:30 a.m., after he allegedly fired at police.

Three officers were transported to Presence Saint Joseph Hospital and another officer was taken to Advocate Sherman Hospital, the Chicago Tribune reported. All had non-life-threatening injuries. The officer who shot the suspect was taken to the hospital for observation, according to a police statement.
