Update via The Los Angeles Times:
Oficials have closed all Los Angeles Unified School District campuses Tuesday morning after a bomb threat was called in to board member,.
Authorities said they plan a search operation of all LAUSD schools after an "unspecified threat was received."
The move comes less than two weeks after two shooters killed 14 people in San Bernardino in what was the deadliest terrorist attack on U.S. soil since 9/11.
It is unclear when the threat was made and to which school board member, but the situation prompted the LAUSD to close all schools effective immediately, according to the Los Angeles school police.
Students and staff were directed to stay away from all campuses.
