DALY CITY, Calif. (AP) — Police officers have stood down after concluding that reports of shooting at a San Francisco Bay Area medical building were unfounded.

SetonMedicalCenter spokeswoman Mary Coady says police responded to the shooting Wednesday afternoon at the building, located at 1500 Southgate Avenue in Daly City, Calif.

Patients and staff members were evacuated from the building with their hands held over their heads.

Coady says the building, which houses about 40 medical practitioners, was evacuated but that the main hospital remained open.

Daly City Police Lt. David Mackriss told the San Francisco Chronicle that a doctor reported seeing a gunman and hearing gunshots. But after a search, no victim or suspect was found, and investigators declared the building clear just before 5 p.m.
