A three-alarm blaze occurred early Saturday morning, around 4 a.m., in a small industrial space at 3050 Broadway on Oakland's Auto Row. Firefighters arrived to find flames shooting 20 feet in the air from a marijuana grow operation with upwards of 100 plants.

The blaze occurred in a building next door to a vacant lot where a Victorian burned to the ground in 1999, killing a firefighter in the process. Approximately $500,000 in damage was caused by Saturday's fire, and officials have declared it a crime scene. Investigators plan to obtain a search warrant for the property, and, obviously, track down the owners of those plants.

No one was injured in the blaze, and no one appeared to be attending to the grow at the time.
