An arson suspect was arrested soon after a massive fire erupted at a warehouse in Ontario, California.

Now, the San Bernardino County District Attorney’s Office has filed multiple charges against him.

The fire was reported around 12:30 a.m. Tuesday, according to the Ontario Fire Department. More than 100 firefighters were on scene battling the flames.

“This fire was very quickly identified as suspicious in nature,” said Deputy Chief Mike Wedell. “There was a subject of interest identified very early on in the incident. That subject has been arrested.”

There were no injuries reported.
