A U.S. postal worker was shot while on-duty on Chicago's South Side Thursday morning, officials said.
Authorities at the scene reported a 24-year-old woman was shot four times in the stomach just after 11:30 a.m. in the 9100 block of South Ellis in the Burnside neighborhood, according to Chicago police.
The U.S. Postal Inspection Service said inspectors from its Chicago division were responding to the scene and working with the Chicago Police Department on its investigation.
"The carrier was on duty when she was shot and taken to an area hospital," Postal Inspector Silvia Carrier said in a statement.
Chicago police said the woman, who they do not believe was the intended target, suffered wounds to the back of both legs, her buttocks area, her stomach and the back of her head. She was transported to University of Chicago Hospital in critical condition.
According to authorities alleged shooters were "in vehicles driving by at a high rate of speed when the shots were fired."
No one was in custody as of 2:30 p.m., police said, and Area 2 detectives were investigating.
