Firefighters battled a four-alarm blaze at General Motors’ Advanced Design Center in Pasadena on Wednesday evening, Oct. 22, authorities said.
The fire was reported around 5:50 p.m. on the 600 block of Sierra Madre Villa Avenue, according to city spokeswoman Lisa Derderian, at the nearly 150,000-square-foot facility.
As of 7:15 p.m., crews had located the source of what Derderian described as a “very stubborn” fire, though it had not yet been fully extinguished. The cause remains under investigation.
The blaze was upgraded to a four-alarm fire, requiring additional resources and a multiple-agency response.
There was no immediate information on the cause of the fire.
No civilian injuries were reported. Derderian said there was a brief scare involving a firefighter who could not be located. The firefighter was quickly found and exited the building and did not require hospital transport.
