New York City officials, though, said a similar threat was sent to schools early Tuesday morning.

The Los Angeles Times reports that officials will conduct searches at all schools Tuesday after a threat was called into a school board member, though it was unclear which school it was.
In a statement, the LAUSD said: “All LAUSD schools are closed today to ensure safety of students. Parents should retrieve students at reunion gates with proper ID.”
LAUSD Superintendent Ramon Cortines said he got word of the threat around 5 a.m. PST.
Los Angeles School Police Chief Steve Zipperman said the threat came in electronic form and was sent to several unspecified campuses.
