Arson and bomb investigators were looking into what caused the devastating San Diego County wildfires, several of which burned close to roads, officials confirmed Thursday.

Several people were interviewed at the scene of the Lakeside fire near Aurora Drive when it started just after 5 p.m. Wednesday, said San Diego County Sheriff Bill Gore.

Authorities have urged the public to call local law enforcement if they see any suspicious activity. Gore said "nothing is too small" to report.

Escondido police briefly detained a man Thursday afternoon but released him.

The wildfires raging across Southern California have scorched more than 10,000 acres, with crews struggling to protect hundreds of homes from advancing flames.

At a news conference Thursday afternoon, officials said an 18-unit apartment complex in Carlsbad and at least seven houses had been destroyed in the more than half-dozen brush fires that have flared up in San Diego County since Wednesday.

San Diego County Supervisor Dianne Jacob urged residents to heed evacuation orders as they come.

“That’s the No. 1 priority, is to save life and then to save property,” she said.

Even though fire conditions had improved slightly, she said the county remained on high alert for "dramatic" flare-ups.

“We are not out of the woods yet,” she said.
