Officers responded to the 5500 block of McDonald Avenue at about 5:40 p.m. after receiving a call from a concerned person about a mentally depressed relative in possession of several firearms, police said.
The caller also mentioned that the relative had been making suicidal threats, according to police.
Negotiators talked with the male by phone, and heard several shots being fired from inside the home, police said.
Officers surrounded the home and also heard a number of shots being fired, according to police.
After about 45 minutes attempting to diffuse the situation, the male refused to surrender and threatened to shoot the officers. He then disconnected his call with negotiators, according to police.
Additional officers responded to the area in an armored vehicle, and an armed man came out of the home and fired shots at the officers in the vehicle, police said.
Officers fired back and hit the man at least once, and he retreated back inside the home, according to police.
The man was rescued by officers and was transported to a hospital where he is being treated for life-threatening injuries, police said.
The incident remains under investigation.
