A fire has burned about an acre of brush alongside Sierra Highway between Placerita Canyon Road and Golden Valley Road in Newhall.
Around 9:40 a.m. Monday, fire crews responded to the northbound side of Sierra Highway for two spot fires burning along the road, according to Marvin Lim, a spokesman for the Los Angeles County Fire Department.
About 115 firefighters were on the scene, and as they were putting out the two spot fires, they rushed to the bottom of the hill where smoke began to fill the air.
“There is an arson investigation right now,” said Lim.
Although the “Sierra Incident” did not threaten any structures, the northbound side of Sierra Highway was closed to drivers for safety reasons.
The Fire Department closed the incident at 11 a.m., according to fire officials.
