Four men were being questioned tonight in connection with a mob attack of a crowd of people in Lakeview early this morning that left one man with a broken jaw and was videotaped by someone who was with the attackers, authorities said.



The attacks happened about 1:10 a.m. at Clark Street and Cornelia Avenue, just south of Wrigley Field, when between 8 and 10 people jumped out of a white stretch limousine, police said.



Several people from the limousine started punching and hitting another group of people, and someone who was with them began recording the attack on video, said Chicago News Affairs Officer Daniel O'Brien.



Following the attacks, a 27-year-old man was taken to Advocate Illinois Masonic Medical Center with head injuries, including a broken jaw, police said. Two other men, 22 and 27, also were injured and spoke to police, but were not taken to a hospital.



The most seriously injured man told police that three people came up to him and began punching him in the face, sending him to the ground, police said. The 22-year-old also was punched in the head by three men, he told police. The other 27-year-old was punched in the head and chest, also by three people.



Officers arrived on scene near 3500 N. Sheffield Ave. soon after and were flagged down by witnesses, who pointed out some of the attackers, including one man who was not wearing a shirt, police said. Officers were able to arrest four men, two age 32, two age 31, identified by victims, police said, adding that two of the four are on parole.



One officer suffered a knee injury when one of those identified as an attacker swung at the officer and struggled with the officer, O'Brien said.



The person captured the attack on video was with the attackers, but was not arrested. Police said the other attackers either fled in the limousine or on foot.



The four arrested could face felony charges of mob action, resisting arrest and aggravated battery, police said, but no charges have been filed against them as the investigation continued Sunday night by Area North detectives.
