A threat at Castle Park High School in Chula Vista early Tuesday resulted in a short lockdown before police determined the campus to be safe.
At 10:15 a.m., the school received a phone call of a bomb on campus and notified police, the Chula Vista Police Department said.
The school was on lockdown for nearly an hour before the CVPD conducted a physical sweep of the school and found no devices, police said.
There are no suspects in custody and there is no continuing threat to the public, police said, though the investigation is ongoing in hopes of finding the suspect that phoned in the threat.
No injuries were reported, Sweetwater Union High School District official Manny Rubio said.
