Police are looking for a suspect

Los Angeles CNN  — 

A joint task force Saturday was investigating a string of 35 fires across several Southern California communities, and one mayor called them a “new form of domestic terrorism.”

Six of those fires spread to nearby structures, fire officials said.

“This is an arsonist working,” Los Angeles Deputy Fire Chief Mario Rueda said.

He did not disclose if there were any patterns to the fires, but he said that what they’ve seen make officials believe they were intentionally set.

Thirteen of the fires were in Los Angeles, and six in Los Angeles County, in West Hollywood.

Investigators were looking for surveillance camera footage or witnesses to the fires, Rueda said.

“These (fires) can certainly lead to death or serious injury of folks,” Rueda said.

Police responded at 12:45 a.m. by issuing a citywide tactical alert.
