San Francisco police say no merit to report of active shooter in Potrero Hill

SAN FRANCISCO (KGO) -- There was a frightening gun scare in San Francisco's Potrero Hill neighborhood on Monday after workers were told there may be someone with a gun in their building.

Police went floor to floor at an office building at 350 Rhode Island Street, which includes Samsara and a Sutter Health clinic.

There were two calls. At 12:15 p.m., an employee called to report a man with a knife or a stick. At 12:45 p.m., another call was made about an active shooter inside the building.

That prompted the large police response.

Lucas Walker was outside the building when they arrived. "I was surprised and worried. I was outside when it happened so I tried to connect with my co-workers that everything was OK," he said.

Inside the building, police went door to door but found no threat.
