ONTARIO, Calif. (From news reports) -- Video circulating online appears to show a person suspected to be a warehouse employee igniting a fire at the California facility while making ominous remarks.

Fire crews responded to a blaze at the 1.2 million-square-foot Kimberly-Clark warehouse for paper products in Ontario shortly after 12:30 a.m. on Tuesday, April 8, according to a joint press release from the Ontario Fire Department and Ontario Police Department.

About 175 firefighters and 15 truck companies responded to the six-alarm fire, officials said. Crews first went inside to battle the flames but had to pull back and fight it from outside as it quickly spread. The fire was contained to the building, and crews worked into the evening to put it out, per the release.

A neighbor recounted the scene to KABC.

"It was more than 'Wow,' it was like, 'Oh my god. We need to run,'" Teri Cruz said, per the news station. "Yes, because it was just a big blaze of fire."

Officials said they thoroughly searched the warehouse and initially reported one person missing. That individual was later found and identified as 29-year-old Chamel Abdulkarim, an employee of NFI Industries, a third-party distribution company handling Kimberly-Clark products.

A video reportedly posted to Facebook by someone believed to be Abdulkarim shows a person setting stacks of paper products on fire with a lighter, with a voice heard in the background.

"All you had to do was pay us enough to live," a person is heard saying in the clip, per CBS News, KTLA, and the Los Angeles Times. "There goes your inventory."

Police have arrested Abdulkarim on multiple arson-related charges, per the release. He is being held at the West Valley Detention Center without bail, they said. It's unclear if he has entered a plea or retained an attorney to speak on his behalf.

While officials have not disclosed a possible motive for the fire, they said they are looking into the suspect's social media activity.

"We have had reports that he did give some information on social media," Ontario Police Dept. Cpl. Emily Williams told KTLA. "We can't go into specifics as to what that information is."

Officials are asking anyone with further information related to the case to contact Detective Ryan Ronveaux at (909) 408-1748.
