Editor's note: This story was updated to reflect a follow-up email sent to parents on Wednesday afternoon.

Manhattan Beach Middle School was briefly shut down on Wednesday morning over reports of a bomb threat, which police later deemed not to be credible.

According to an email from MBMS Principal Luke Olesiuk to parents, the school received a report from a student who overheard another student make a statement about a possible bomb threat. 

The school was placed on lockdown, and then students and staff were evacuated to the blacktop. After Manhattan Beach Police were able to provide the all-clear (with the assistance of an explosive detection canine), students were able to return to class. 

"There is no indication that this was a credible threat, and all students and staff are safe," wrote Olesiuk in the email to parents. "At this time, we thank the student who had the courage to report what they heard. The school is now returning to normal operations."

Parents received the first email about the incident just before 10:00 a.m. They were asked not to come to the school to pick up their children. A second email letting parents know that the all-clear was given was sent at 10:30 a.m. 

Afternoon Update Sent


At 2:00 p.m., Olesiuk sent the following email to MBMS parents: 

This morning, a student overheard another student make a statement about a possible bomb threat. The student immediately reported this to a teacher, who immediately reported it to school administration. We called a shelter-in-place as we gathered information and then quickly transitioned to a campus evacuation. MBPD assisted with the investigation and conducted a search of campus with a K9 unit with special training to detect explosives. No explosives or traces of explosives were found, and the campus was cleared to return to normal operations.

We are sorry for the disruption that was created by the poor decision of the student who made the statement. We will be issuing disciplinary consequences consistent with Board Policy and California Education Code. As you know, we are prohibited from sharing information about individual students, so we are not able to provide additional information beyond that.

We are incredibly grateful to the student who heard the statement and took immediate action, as well as the staff member to whom the student felt safe reporting and who also took immediate action. The student’s reporting took strength and bravery, and the actions of that student and our staff member allowed us the opportunity to ensure that the campus and our students were safe. 

We know that this kind of situation can be frightening and unsettling for everyone. We will have additional counseling support from our partners with BCHD who will be available on site at MBMS tomorrow in the Wellness Center. Please let your student know that if they need someone to talk with, they are welcome to come to the office during the day today or anytime tomorrow. If your student is in need of additional support this afternoon, allcove is open for drop-in support at their Prospect Avenue location. 

MBMS will be continuing with normal operations for the remainder of the week. We want to again thank the students and staff who acted quickly by following our protocol of “See/Hear Something, Say Something” and ask everyone to continue to stay vigilant and share any concerns with a trusted adult. We also ask that everyone please remind students once again about the serious consequences that can result from making comments, even in jest, about weapons or dangerous objects. Thank you also to our staff and parents who were patient, understanding, and supportive throughout the day.

The school also sent resources to help families talk to their students.

On Thursday, MBMS counselors and psychologists will be on hand to support students, and the school will offer additional mental health support for students through the district's partnership with Beach Cities Health District.


Parents, Staff Critical Over MBMS Communication


Olesiuk and MBUSD administrators have been targets of criticism since the March 19 discovery of a student with an unloaded handgun in his backpack. 

Parents' and staff members' ire over a lack of timely communication about the incident spilled over into a school board meeting the following week. MBUSD then organized a town hall meeting, held on April 7, which brought more community members who expressed anger about the way the incident was handled.

In May, the Manhattan Beach Unified School District rolled out a series of initiatives meant to address safety concerns. Those steps included bringing on three outside consultants: 
  • ESMP, to assist with refining comprehensive school safety plans, safety protocols, and crisis communications protocols; 
  • Chameleon Associates, to assist with school safety measures; 
  • ICS4Schools, to assist with emergency trainings. 

Over the summer, ICS4Schools will also be assessing campus sites, while ESMP will work with school management teams and Chameleon on best practices for physical security.

In the fall, the district will hold security awareness trainings, implement CSTAG recommendations, and will hold additional exercises and drills, including a district-wide Great Shake-Out drill on October 16.
