Four people were hurt in a shooting Saturday in Humboldt Park on the West Side.

They were involved “in an altercation” with an unknown person about 4:20 a.m. at a restaurant in the 3500 block of West North Avenue, Chicago police said.

After the altercation turned physical, the four left the restaurant, got in a Jeep Cherokee and the person they were arguing with pulled out a handgun and fired shots at the car, police said. The Jeep caught fire, collided with a parked car and came to a stop.

A 30-year-old man was hit in the arm, leg and chest, police said. He was taken to Mount Sinai Hospital in serious condition.

A 45-year-old man suffered a gunshot wound to the shoulder and was taken to Stroger Hospital in serious condition, police said. A third man, 43, was hit in the back and was taken to the same hospital. His condition was stabilized.

The fourth person, a 24-year-old man, was grazed in the hand and refused medical attention, police said.

No one is in custody as Area North detectives investigate.
