"Out of an abundance of caution for both the students and teachers at the school, the school was locked down and police remained at the school to ensure their safety," police said in a release.
The lock down was ended by 3 p.m. PT without any injuries. Police did not elaborate on the nature of the threats.
"Our goal is now focusing on the investigation to try to find out who made these threats and whether these threats were credible," said Sgt. Randy Fincham.
