Video obtained by the entertainment website RadarOnline.com purportedly shows last week's accident on the set of Transformers 3 that left a Chicago extra seriously injured.
The website claims the footage shows vehicles traveling down Cline Avenue, in Hammond, Ind., last week.
A cable pulling one of the vehicles snapped and crashed through the windshielf of a vehicle being driven by 24-year-old Gabriella Cedillo. Her vehicle, a light-colored 2006 Toyota, can be seen striking and sliding along the roadway's median.
Shortly after the incident, the voice of a man identifying himself as John Silvia is heard over a radio:
"FYI, per request of the police department, everything involving this gag is officially impounded. You are not to remove equipment, you are not to touch equipment due to the special effects: the trucks, the rigs, all of the wire, anything."
Cedillo was airlifted to Loyola Medical Center in Maywood and underwent emergency surgery for a serious head injury. The hospital last Friday said Cedillo was listed in critical condition. RadarOnline.com reported that she is in a medically-induced coma.
Plans to continue filming in the Chicago area were scrapped after the accident.
"Right now we're in the process of investigating the causes of the accident, as in any violations of Indiana workplace safety rules that might have taken place that led up to that accident," said Marc Lotter, a spokesman for the Indiana Occupational Safety and Health Administration.
There's been no comment from the producers of the movie about RadarOnline.com's video.
