A brush fire sparked near a riverbed in Montebello, a suburb east of downtown Los Angeles, halted operations at an oil field and prompted the evacuation of a park, according to the Associated Press.
Montebello authorities say a 45-year-old man has been arrested on suspicion of arson, with the homeless suspect being identified as Arturo Aguilar.
The Lincoln Fire was 60 percent contained by Monday afternoon and had scorched 225 acres, L.A. County Fire Department spokesperson David Dantick told KPCC.
"At this point, there is no threat to homes," said Dantick. "We want to get a good hold of it as much as possible today because we don't want to get these high temperatures that we had the last couple of days."
On Sunday night, residents of neighboring communities were under voluntary evacuation, NBC4 reports:
"Flames right up in here is what scared me because that's when they told us that we needed to evacuate because it (the fire) was swinging around," Sandra Estrada said.
Shooting range areas of the Whittier Narrows Recreation Area and Legg Lake, which was providing water for firefighting efforts, were evacuated just before 6 p.m. Firefighters issued voluntary evacuations for more than 30 homes on Muscatel and Hazel avenues and Darlington Street in South San Gabriel, according to the Los Angeles County Sheriff's Department.
