All schools in Los Angeles, the second largest school district in the United States, were closed on Tuesday after officials reported receiving an unspecified threat to the district and ordered a search of all schools in the city.
“It was not to one school, two schools or three schools, it was many schools, not specifically identified … that’s the reason I took the action that I did,” Ramon Cortines, superintendent of the school system, told reporters at a press conference that began shortly before schools were to begin opening.
The threat came via an electronic message, Cortines said.
Los Angeles police and the FBI were notified of the threat and were investigating, officials said.
