A woman died Thursday morning at Chicago O’Hare International Airport after getting caught in a baggage carousel, officials told ABC News.

The woman, who has not yet been publicly identified, was 57, according to the Chicago Police Department.

The woman was a member of the public and not a worker at the airport, according to a spokesperson for the Department of Labor.

Emergency responders were called to Terminal 5 at about 7:45 a.m. Thursday following reports of a woman “pinned in machinery,” the Chicago Fire Department said.

Upon arriving to the scene, they found the woman “entangled in the conveyer belt system used to move baggage,” fire officials said.

Medics pronounced the woman dead at the scene.

Police said surveillance footage of the area showed the woman “entering an unoccupied restricted area at 2:27 a.m.”

She was discovered at approximately 7:30 a.m., police said, and emergency responders were called to the scene.

The area has been declared a crime scene, and the Chicago Police Department is investigating.
