A 17-year-old student at a Hacienda Heights high school was arrested Friday on suspicion he wrote a threatening note that prompted a lockdown Monday at the campus, authorities said.
Hacienda La Puente Unified School Districtpolice officers arrested the Wilson High School student earlier Friday, school district spokesman Sean Rossall said.
The suspect was taken to the sheriff’s Industry station for booking.
The student’s name has not been released because of his age.
The arrest was the result of an ongoing investigation, which was triggered by a report of the threatening note from a student at Wilson High School on Oct. 26, Rossall said.
Following the initial investigation and search of the school, which was found to be safe, school police conducted an investigation that led to the student’s arrest.
“We want to thank our school police for their diligent work in keeping our schools safe,” district Superintendent Cynthia Parulan-Colfer said. “As a community of educators, our goal is to provide every student with a safe learning environment.
“We work hard to accomplish this every day, and we are committed to taking every action to ensure that we protect the students in our care,” Parulan-Colfer said.
