A man has been arrested in Los Angeles after neighbors said they saw him trying to start a fire with a “propane tank or flamethrower."

Los Angeles Police Chief Jim McDonnell said three people have been arrested for arson in the past few days outside of recent wildfire zones.

In the case of the Eaton Fire, the investigators are likely to use magnets to help them hunt for the tiny, melted pieces of metal that could have been shed by power lines if they slapped together. But the existence of the metal doesn’t necessarily indicate that’s how the fire started, Nordskog said.

A new task force focused on fighting crimes related to the devastating Los Angeles wildfires was announced Thursday as residents work to recover and rebuild. The Joint Regional Fire Crimes Task Force is comprised of federal and local law enforcement agencies that will investigate fire-related crimes and prosecute those seeking to exploit the wildfire crisis,

Two more people are behind bars for allegedly setting small fires in Los Angeles amid high fire-danger conditions and as crews continued efforts to fully contain a pair of destructive blazes.

Los Angeles police said three people were charged with arson in separate incidents this week after they were caught lighting fires near where the massive, deadly blazes have torn through parts of Southern California.
