A 24 year-old woman named Gabriella Cedillo, was rushed to the hospital and underwent brain surgery after a stunt gone terribly wrong during shooting on set of Michael Bay‘s “Transformers 3” movie in Chicago on Wednesday (September 1).

“She had to have brain surgery last night after the accident happened,” confirmed a source who works on the set. “We don’t know how she is doing now, we’re waiting to hear.”

Gabriella, who was an extra on set and not a stunt woman, was inside her own car being towed by another vehicle when the tragic accident happened. The filming has been shut down just one day after completion.

“The vehicle was being towed by another vehicle,” fellow extra Blaine Baker told Chicago station WLS. “The cable between the two vehicles broke. It whipped around and sliced through the woman’s car and sliced through her skull, apparently.”

The authorities have issued an official statement about this accident: “Preliminary investigation revealed that shortly before 7 pm, the movie crew was filming a stunt using numerous vehicles and drivers. During this stunt, an object struck a 2006 Toyota, hitting the vehicle, and then went through the windshield hitting the driver.”

Surprisingly, Paramount Pictures has not released a statement yet.
