Four Jewish schools across the United States were targeted by bomb threats within days of one another, forcing the evacuation of hundreds of students and staff members in Brooklyn and Florida and triggering a frightening lockdown at a Jewish school in Los Angeles. Authorities have since determined that all four threats were hoaxes, although investigations into the incidents remain underway.
The incidents, which occurred between October 9 and October 12, targeted two Brooklyn yeshivos, a Jewish preschool in Boca Raton, Florida, and a Jewish middle and high school in Los Angeles. The threats prompted significant police responses, including searches by specialized emergency units and bomb-sniffing dogs, and renewed concerns about the security of Jewish educational institutions.
The first two threats were reported Friday morning, October 9, when the Yeshivah of Flatbush Joel Braverman High School and the United Talmudical Academy of Williamsburg received threatening telephone calls just minutes apart.
According to the NYPD, the initial call came into the Yeshivah of Flatbush, located at 1609 Avenue J, at approximately 9:54 a.m. Six minutes later, a similar threat was received at the United Talmudical Academy, located at 590 Bedford Avenue in Williamsburg.
Both schools immediately implemented emergency procedures, evacuating students and faculty while police officers secured the surrounding areas.
NYPD Emergency Service Unit personnel and K-9 teams were dispatched to the buildings to conduct searches for possible explosive devices. Police vehicles and fire trucks surrounded the affected locations, and nearby streets were temporarily restricted as authorities investigated.
Video footage from Flatbush showed students gathered outside near school buses while officers examined the premises. In Williamsburg, emergency vehicles lined the street as police secured the area around the yeshiva.
After completing their searches, authorities determined that neither threat was credible. No explosive devices were discovered, and students and staff were permitted to return to their classrooms.
The NYPD confirmed that no injuries had been reported and that no arrests had been made in connection with the incidents.
The Yeshivah of Flatbush sent a message to parents during the emergency, advising them not to come to the school while police and security personnel handled the situation.
The threats came just two days after the third anniversary of the October 7 Hamas massacre in Israel, a period of heightened concern among Jewish communities over possible antisemitic incidents.
Three days after the Brooklyn incidents, another Jewish educational institution was forced to evacuate when a bomb threat was received at the Donna Klein Jewish Academy preschool in Boca Raton, Florida.
The threat, reported Monday afternoon, October 12, prompted an emergency response at the Jewish Federation of South Palm Beach County’s campus, which houses several Jewish educational and communal organizations.
The affected preschool is located on the Toby and Leon Cooperman Campus, a large Jewish communal complex that also accommodates the Adolph and Rose Levis Jewish Community Center and other institutions.
Palm Beach County Sheriff’s Office deputies responded to the scene and searched the affected facilities while students and staff were evacuated as a precaution.
The incident caused traffic disruptions in the surrounding area, including difficulties for parents attempting to reach nearby schools during dismissal.
A student at the nearby Katz Yeshiva High School described the disruption, explaining that students were informed of the emergency through a school announcement.
“I was in my classroom during English and we just had an announcement on the loudspeaker that there was a bomb threat at the school next door to us. Traffic was blocked, because they weren’t letting any vans or cars in for carpool.”
“They told us we needed to stay inside for a while, and they’d tell us when it was time to come out,” the student added.
Authorities eventually determined that the threat was unfounded, and the Jewish Federation confirmed that the threatening call had been fraudulent.
All students and staff members were reported safe, and children were reunited with their families following the police investigation.
Rep. Jared Moskowitz, a Jewish Democrat representing a Florida congressional district, condemned the incident and expressed relief that no one had been harmed.
“Let’s be clear: there is no cause in the world that’s served by scaring children. If your grievance leads you to a K–12 school, you’re the problem,” Moskowitz wrote on social media.
A similar emergency unfolded Monday at Milken Community School, a private Jewish middle and high school in the Los Angeles area.
Police initially responded to a report of an active shooter at the school, but authorities subsequently clarified that the emergency involved a bomb threat.
The school was placed on lockdown as officers investigated the report, with students instructed to follow emergency security procedures inside their classrooms.
One parent described the frightening experience of a child who was attending class when the threat was received.
“My son was in math class when the bomb threat was called in,” the parent said.
“They had to pull down the shades on the classroom door and windows, lock the door, turn off the lights, and sit under their desks,” the parent explained.
“It sounds pretty intense to have to prepare the classroom like that. He was scared and nervous.”
The Los Angeles Police Department later confirmed that the threat was a hoax and that no actual danger had been discovered at the school. An investigation into the source of the call remains ongoing.
Despite the frightening experience, the parent said the family’s confidence in the school’s security arrangements had not been shaken.
“Jewish schools tend to have higher-caliber security than at non-Jewish schools, so I’m not worried,” the parent said. “I don’t feel like it’s unsafe for my son to go there. He had no problem going to school yesterday or today.”
The series of incidents has renewed attention to the disruption caused by fraudulent emergency threats, which can force schools to suspend classes, evacuate buildings, and mobilize substantial police resources even when no actual explosive device exists.
Security professionals warn that such threats should not be dismissed merely because they are ultimately determined to be false.
Richard Priem, chief executive officer of Community Security Service, said the incidents must be considered against the broader backdrop of threats and attacks targeting Jewish communities in the United States and abroad.
“We should not look at these incidents in isolation and base our assessment on that,” Priem said.
“We’re living in an era where, over the last 18 months, we’ve had a number of serious attacks on the Jewish community in the United States and abroad. That should warrant all of us working and thinking about this to take the threats against our community seriously.”
Priem explained that bomb threats can serve as a means of intimidation even when those responsible have no intention or ability to carry out an actual attack.
“It’s very easy to make a bomb threat, and they don’t necessarily indicate advance preparation,” he said.
“We have seen a lot of bomb threats over the years that were meant to intimidate, harm and dissuade Jewish community members from participating in Jewish life.”
Michael Masters, national director and chief executive officer of the Secure Community Network, similarly emphasized the importance of advance preparation and coordinated emergency procedures.
“We tend to see these bomb threats come in waves,” Masters said.
“The difference in how these threats are responded to usually comes down to the training, the preparation and the plan that the institution puts in place. It’s so important for institutions to have a plan, to review it, and to implement it prior to these calls coming in.”
Masters drew a parallel between school security preparations and the Torah account of Noach, emphasizing the importance of taking precautions before an emergency develops.
“It’s absolutely vital that we work to be prepared,” he said. “This week, we read the parsha of the story of Noah. When did Noah build the ark? Before it began to rain.”
The latest threats recall a widespread campaign of bomb hoaxes targeting Jewish institutions in 2017, when numerous Jewish community centers and schools across the United States and other countries received threatening calls.
That investigation eventually led Israeli authorities to arrest an Israeli-American teenager, who was subsequently sentenced to prison for his involvement in the threats.
Authorities have not established whether the four latest incidents were coordinated or carried out by the same individual or group. Investigations into the threatening calls are continuing.
