ALTADENA >> Deputies and explosive-sniffing dogs searched the campus of an Altadena elementary school early Wednesday after someone phoned in a mob threat, but ultimately found nothing out of the ordinary, authorities said.
An unidentified male adult called the school shortly before 10 a.m. “and indicated he was going to blow up the school,” Los Angeles County sheriff’s officials said in a written statement. The threat involved no further specifics.
Deputies responded to the campus, 593 W. Woodbury Road to investigate.
“The deputies conducted a search of the school, along with the assistance of four K-9 bomb detection units and school personnel who were familiar with the campus,” according to the statement. “No explosive devices, or foreign unfamiliar devices were detected. Additionally, there was no known motives and there was no suspect identified.”
The school resumed normal operations once deputies sounded the all-clear.
Anyone with information can reach the sheriff’s Altadena Station at 626-798-1131. Tips may also be submitted anonymously to L.A. Regional Crime Stoppers at 800-222-8477.
