ANTIOCH (CBS SF) — Firefighters in Antioch are investigating a four-alarm apartment fire that broke out Friday night and sent three people to the hospital.
The blaze was first reported around 10 p.m. in the 3900 block of Delta Fair Boulevard, Contra Costa Fire Protection District Capt. George Laing said.
Four people were treated at the scene for smoke inhalation and three were taken to the hospital.
Firefighters were able to extinguish the fire before midnight.
It appears the blaze started as a vegetation fire and then spread to several structures, according to the Contra Costa Fire Protection District.
There were 18 units in three buildings and one acre of vegetation damaged in the fire.
The damaged caused by the fire is estimated at $990,000.
The blaze may have been started by fireworks, as there were earlier reports of fireworks in the area, according to Laing.
