FREMONT (CBS SF) — Giant plumes of black, gray and white smoke billowed in Fremont on Sunday afternoon as the vacant former site of Redeemer Church burned.

When firefighters arrived, fire, heat and smoke were widespread in the building at 41354 Roberts Ave., the Fremont fire department said in a tweet but, thanks to an aggressive fire attack, firefighters prevented the blaze from extending to nearby homes.
