Del Oro High School and Confluence West High School in Loomis, California, were placed on full lockdown at approximately 10:40 a.m. after reports of an alleged threat directed toward the campuses. The Placer Union High School District confirmed the incident and immediately activated established emergency protocols to ensure the safety of all students, staff, and faculty members.
Law enforcement agencies, including the Placer County Sheriff’s Office, responded swiftly to the situation. Officers arrived on scene and secured a perimeter around both campuses while conducting a thorough assessment of the reported threat. To assist with situational awareness, California Highway Patrol (CHP) air support was also requested, providing aerial monitoring of the surrounding area as part of the coordinated response effort.
Students and staff were instructed to shelter in place as lockdown procedures were implemented across both schools. Classrooms were secured, doors were locked, and all movement was restricted in accordance with safety guidelines designed to minimize risk while law enforcement investigates. Officials emphasized that these precautionary measures are standard protocol during potential threat situations.
Authorities have urged parents and guardians not to come to the school campuses during the lockdown. Officials warned that increased traffic or presence near the schools could interfere with emergency operations and potentially compromise safety. The district stressed that allowing first responders full access to the area is critical to ensuring an effective and controlled response.
School officials also assured families that communication will continue as updates become available. However, they noted that information may be limited while the situation remains active, as law enforcement works to verify the credibility of the reported threat and secure the environment.
At this time, no further confirmed details have been released regarding the nature of the threat or whether it has been deemed credible. Investigations remain ongoing, and authorities are actively gathering and assessing all available information.
Both the school district and law enforcement agencies have reiterated their commitment to the safety and well-being of students and staff. The community is being asked to remain calm, avoid spreading unverified information, and wait for official updates as the situation develops.
