Three people were wounded in a shooting on a party bus early Sunday on the North Side.
An argument erupted at 1:53 a.m. and a male on the bus opened fire while it was traveling in the 500 block of West Irving Park Road, according to Chicago Police.
One man, 22, was shot in the head and taken in critical condition to Illinois Masonic Medical Center, police said. Another man, 33, suffered a gunshot wound to the chest and was taken to Northwestern Memorial Hospital, where his condition was stabilized.
A 31-year-old man, who may have been a shooter, had a gunshot wound to the left hand and was also taken to Masonic Medical Center, police said. The circumstances under which that man was shot were not immediately clear, but the man was being questioned by detectives early Sunday. No other injuries were reported.
Officers could be seen investigating on a white party bus, parked under the Lake Shore Drive viaduct on Irving Park.
