A bomb threat prompted the evacuation of the Kehillah Jewish High School in south Palo Alto on Thursday afternoon, police said. No bombs were found.

A man called the administrative office at the school to make a threat, according to a news release. School officials called the the city's emergency dispatch center shortly before 3 p.m. and evacuated the roughly 250 students and staff who were on campus at the time.

Officers cordoned off the school at 3900 Fabian Way and searched the property with a police K-9 that is certified in explosives detection, according to the news release. They determined that no bomb was present and are now looking for the caller.

There have been no similar phoned-in bomb threats recently in Palo Alto, according to the police. There was, however, a recent incident at Jane Lathrop Stanford Middle School in which a student scrawled a bomb threat on a stall of the girls' bathroom. Investigators identified that student and deemed the threat not credible.

"We would like to thank the Palo Alto police for their immediate and thorough response and to our parent body for their calm during what was understandably an upsetting experience," Kehillah Jewish High School said in a community statement on Thursday. "It allowed us to do our job and keep our community safe. Our students responded in an exemplary fashion. They have every reason to be proud of themselves."
