San Francisco police raided a marijuana grow operation in the city’s Sunset District Saturday morning, just steps from an elementary school.

Police entered the house in the 2500 block of 41st Avenue at about 8:30 a.m. Saturday, Aug. 6.

“The officers served a search warrant,” Taraval Station Capt. Curtis Lum told the Ocean Beach Bulletin. “No one was arrested.”

Officers seized marijuana-growing equipment including plants and lights, Lum said. He said police also found finished marijuana but did not locate any weapons or cash.

Although no one was arrested, police did detain a 32-year-old woman and a 41-year-old woman. No one else was at the house when police entered.

The house is directly across the street from the playground of St. Gabriel School, a Catholic school serving children from kindergarten through eighth grade. The yard also serves as a parking area for St. Gabriel Church, adjacent to the school. School is out for the summer, but classes will resume Aug. 24.

Lum said he was unsure if either of the women had a medical-marijuana prescription. Although a PG&E truck was at the site of Saturday’s raid after officers left, Lum said the electrical meter in the house had not been bypassed. Indoor marijuana growers often bypass a building’s meter, to either acquire free electricity for growing equipment or to avoid arousing suspicion with a sudden increase in usage.

Lum said he didn’t know how officers knew about the grow operation or what evidence they presented in acquiring the search warrant.
