San Francisco police were dispatched to the JCC on California Street on Thursday after a “threatening message via web form” entered the center, a spokesperson told J.

The threat was “consistent with language previously received by other JCCs and Jewish institutions across the country,” JCC Vice President of Marketing Jami Miskie said. The threat was deemed “not credible”.

In 2020, the San Francisco JCC was one of more than 50 JCCs across the country to receive similar, unspecific bomb threats via email. This threat was also found not to be credible, according to local authorities, and was called “harmful activity” by then-CEO Marci Glazer.

Steven Rosen of San Francisco was sitting in the JCC lobby around 10:50 a.m., “relaxing” and checking his voicemail on his phone, he said, when an alarm sounded.

“It was a screaming alarm,” he said. “People were covering their ears” and the lights were flashing.

About 100 people were told to evacuate the building to a nearby parking lot, including JCC staff, fitness club users and children taking swimming lessons. Rosen noted that a number of people were wearing sportswear.

Police cars sat outside on California Street in both directions, Rosen noted, along with two dark SUVs.

After a “thorough search” of the building by police, Miskie wrote, authorities confirmed the threat was not credible. The JCC resumed its normal programming around 1 p.m.

“Given what has happened in the country over the past two weeks, there is nothing more important than the safety of our community,” Miskie wrote.

The JCC preschool and summer camps were not in session Thursday.
