A suspicious three-alarm blaze broke out Tuesday morning at the old Remington Arms Factory on Barnum Avenue in Bridgeport and firefighters expect to battle the flames into the night.
Video from the state Department of Transportation cameras showed fire coming through the roof of the building and heavy smoke billowing through the air.
Sixty firefighters were called to the scene, including crews from Fairfield, Stratford and Milford, and have been attacking the blaze from the outside for fear of the ceiling or walls collapsing, according to Deputy Fire Chief Robert Petrucelli.
One firefighter sustained minor injuries.
In addition to the factory fire, firefighters also extinguished a blaze that ignited the attic of an apartment building on Helen Street, across from the factory.
Officials are investigating the possiblity that something from the factory may have blown across the street and caused the flames to spread.
Isaac Morales, who lives two blocks from the complex on Barnum Avenue, said he noticed people outside the buildings this morning.
"I didn't think anything of it," he said. "They should [have torn] that place down years ago."
There have been at least three fires at the old factory complex since 2010. All three have happened during the month of August.
In December 2013, demolition began on the site to make way for new developments, which could include a train station, according to reports at the time.
