A 22-year-old assistant teacher has been arrested for leaving bomb threat voice mail messages at a school in San Francisco, police said.
Pablo Munoz of South San Francisco was taken into custody without incident Friday after investigators uncovered that he has behind the bomb threats targeting LePort Monessori School on May 8 and May 16, according to police. No explosives were ever located at the school.
Munoz faces two counts of felony threats and two counts of misdemeanor false reporting of a bomb, according to police.
It is unclear what Munoz's motive was, according to school officials. It does not appear that he was disgruntled, and he does not have a known criminal history.
Munoz has been working at the school since February of 2016, according to school officials. He has not been fired, but he has been placed on administrative leave while an investigation is conducted.
