A teen was taken into custody Wednesday in connection with a bomb threat that prompted the March 24 lockdown at Walnut High School and an evacuation of Mt. San Antonio College, the Los Angeles County Sheriff’s Department reported.
Detectives booked 18-year-old Adrian Mendoza of West Covina for false report of an explosive device, officials said.
A photo of a note stating, “There will be a bomb blown up today both here and Mt. SAC at 2:45 p.m. God be with you all,” was reportedly found at the high school campus.
The Sheriff’s Department responded immediately, locking down the school and sweeping the area.
Mt. SAC administrators decided independently to evacuate students.
Mendoza, a student at both schools, was taken into custody at the Walnut/Diamond Bar Sheriff’s Station and was released on $20,000 bail.
