What was the reaction of New York authorities towards the security threat? [orig

The authorities in Los Angeles have defended their decision to close all public schools for the day because of a suspected security threat. A similar threat was received in New York where the authorities said it was not credible. The city’s police chief called the Los Angeles closure a significant overreaction. Peter Bowes reports: Officials say they decided to close down the entire public school system out of what they called an abundance of caution after they’ve received a threat in an email. The authorities said they would search every school in the district to make sure they were safe for pupils to return.
