A house fire was reported a little before 7 a.m. this morning at a house on the 3900 block of Angelo Avenue in Oakland. During the blaze, neighbors and firefighters learned that the delightful plumes of smoke emitting from the roasting building "led to the discovery of an indoor marijuana growing operation." Sweet. CBS 5 notes, "Eyewitnesses reported a strong smell of marijuana at the site." The fire was under control in about an hour.
