A fire that engulfed a Vallejo police cruiser on Interstate Highway 80 was caused by an electrical failure, police said Friday.
An officer was driving the Ford SUV Thursday afternoon near the Abernathy Road exit in Fairfield when smoke and flames appeared from the back, police said. The fire spread to road flares in the car, which ignited.
The officer pulled over, got out of the car and removed live ammunition from the SUV without injury. Fairfield Fire Department crews arrived on scene and extinguished the fire.
An initial investigation found that a control module in the back of the SUV was the likely source of the fire, police said.
The Vallejo Police Department is continuing to look into the equipment and circumstances around the fire.
