Fire at a home on Arroyo Drive in Orinda brought Moraga-Orinda Fire District firefighters to the scene early Sunday – with the first calls for assistance arriving at 4:53 a.m.

Neighbors reported hearing muffled explosions shortly before seeing smoke and flame coming from the garage area of a home in the first block of Arroyo Drive. Firefighters arrived to find half of the single-story home ablaze.

Firefighters quickly upgraded their response to a 2-Alarm callout, requesting additional apparatus and firefighters as the fire spread and firefighters initiated a search for a resident who could not be immediately located.

In a brief Facebook post, MOFD reported that their attack on the blaze was further complicated by a burning car that rolled down the driveway and into the MOFD fire engine. No residents or responders were injured and the cause of the fire is under investigation.
