Del Oro High School and Confluence West High School in Loomis, California, were placed on full lockdown at approximately 10:40 a.m. today following reports of an alleged threat made toward the campuses. The Placer Union High School District confirmed the situation and immediately activated emergency protocols to ensure the safety of students, staff, and faculty.
Law enforcement agencies, including the Placer County Sheriff’s Office, responded rapidly to the scene. Officers established a secure perimeter around the affected areas while conducting an active assessment of the situation. In addition, California Highway Patrol (CHP) air support was requested to assist in monitoring the surrounding region and providing aerial oversight as part of the coordinated response.
According to early information, students and staff were instructed to shelter in place, with reports indicating that classrooms were secured under lockdown procedures. These measures are standard protocol during potential threat situations and are designed to minimize risk while allowing law enforcement to investigate thoroughly.
Authorities have urged parents and community members not to come to the campuses, emphasizing that doing so could interfere with emergency operations and create additional safety concerns. The district has reiterated that allowing first responders full access to the area is essential for an effective and safe resolution.
Officials have also reassured families that communication will continue as updates become available, though they note that information flow may be limited during active lockdown conditions. This is typical in situations where law enforcement is working to verify threats and secure the environment.
At this stage, the situation remains active and under investigation, with no further confirmed details released regarding the nature or credibility of the reported threat. Authorities are continuing to assess all available information.
School and district officials have expressed their commitment to student and staff safety, while law enforcement continues its coordinated response. The community is urged to remain patient, avoid speculation, and await verified updates as the situation develops.
