Firefighters were able to halt the flames’ progress after a brush fire covered 12 acres in Hacienda Heights Tuesday night.
The fire was reported around 8:20 p.m. near Colima Road and Punta Del Este Drive, according to the Los Angeles County Fire Department. Flames were spreading uphill in light brush to the south of that intersection, in the area of Powder Canyon and Schabarum Regional County Park.
No structures were threatened, officials said.
The blaze was attacked both on the ground and with aerial water drops, Sky5 video showed.
Initial reports indicate it was sparked by fireworks set off in the area, and a criminal investigation would begin once it was fully extinguished, L.A. County Sheriff’s Lt. J. Long said.
It erupted as record-setting heat and dry winds that are expected to linger through Wednesday created hazardous fire conditions across L.A. County.
