DEVELOPING: All of Los Angeles' public schools were closed Tuesday due to a "credible terror threat," officials said.
A member of the LA Unified School District Board of Education reported receiving a bomb threat, police said. It was unclear when the threat was made and which school board member received it, but the situation prompted the district to close all schools effective immediately, and order students and staff to stay away from all campuses.
Schools Superintendent Ramon Cortines said every school in the 640,000-pupil district would be searched. The district, the nation's second-largest, includes 1,124 public and charter schools plus other facilities, including ones for adult language instruction. It covers Los Angeles as well as all or parts of 31 smaller municipalities and employs nearly 60,000 people.
"I think it is important that I take this precaution based upon what has happened recently and what has happened in the past," Cortines said.
Police and the FBI were investigating the threat, which was described as "electronic."
"We received an electronic threat that mentioned the safety of our schools," said LAUSD Police Chief Steven Zipperman.
Cortines stressed at a morning news conference that the threat was broad, and had to be taken seriously.
