Chicago police said four people were wounded overnight in a drive-by shooting on the Near North Side.

Shortly after 3:45 a.m. Wednesday, a gray Acura sedan approached the 1100 block of North Dearborn Street where a gym is located. Someone inside the sedan opened fire, striking four people on the sidewalk, police said.

The vehicle fled south on Dearborn.

A 22-year-old woman suffered a gunshot wound to the right leg, and was taken to Northwestern Memorial Hospital in good condition, authorities said. A 60-year-old man was wounded in the left thigh and was taken in good condition to the same hospital.

A 45-year-old man shot in the right foot and a 24-year-old man shot in the right arm took themselves to Northwestern, where they were both listed in good condition, according to police.

No one was in custody in the mass shooting and detectives were investigating.
