Bomb or shooting threats led to partial evacuations or lockdowns for at least 11 New Jersey schools on Tuesday, NBC New York reported.
The schools received threats from someone who claimed to have placed a bomb. Schools in Teaneck, Garfield, Tenafly, Clifton, Fair Lawn, Leonia, Bergenfield, Englewood, Hackensack, Sayreville and New Milford received warnings, according to NBC New York.
By about 11 a.m. ET, officials said the Tenafly, Leonia, Bergenfield and Teaneck facilities posed no threat, NBC New York reported, citing a source. The other schools were expected to be cleared later in the day.
Authorities told NBC New York that some of the threatening messages were apparently routed through Bakersfield, California.
Clifton police said they did not believe the threat was valid, the report said. However, they took "all precautions" to "ensure safety of the entire school district."
Garfield police took dogs through all schools to check for bombs. Meanwhile, students left the high schools in both Fair Lawn and Bergenfield.
