Classes are proceeding today at Lakeside High School after a former student showed up on campus early this morning with a weapon.

An automated dialer message from Lakeside Principal Jason Moscowitz was sent out to Lakeside parents around 11 a.m. In his message, Moscowitz said he was calling to inform parents of “an incident that occurred on campus this morning before the start of school involving a former LHS student. School staff and officials were prompt in containing the situation. The student was in possession of a weapon but no one was harmed. The student is currently in police custody.”

Mark Dennis, coordinator of community and media relations for the Lake Elsinore Unified School District, said the incident took place sometime around 7 a.m. He did not confirm what type of weapon or how many were brought to the campus.

Dennis could not confirm what prompted the student to bring the weapon to campus.

“He sought out a teacher,” he said. “I think it was more of a cry for help.”

Dennis said the former student, whose identity has not being released, is a high school student at another campus.

According to Dennis, “the student quickly surrendered to school authorities. The incident did not develop into a further threat or tragedy. The school did not go to a lockdown.
