New York City officials say they received the same threat that led to the closure of the Los Angeles school system but quickly concluded that it was a hoax.

Mayor Bill de Blasio said Tuesday morning that he was “absolutely convinced” there was no danger to schoolchildren in New York.

New York Police Commissioner William Bratton said he thought Los Angeles officials overreacted by deciding to close the nation’s second-largest school system.

He said a school superintendent received the threatening email Tuesday morning.

Bratton said the person who wrote the note claimed to be a jihadist but made errors that made it clear the person was a prankster.
