On September 18, local time, the U.S. Federal Bureau of Investigation and New York City Police said that the same day, a 16-year-old student was arrested for allegedly threatening to shoot at a high school in the Queen's District of New York City.

It is reported that the police received an alarm that morning, saying that someone posted a post on social media threatening to "shoot and strafe the school". Subsequently, new york Police Department officers entered Cardoso High School in Queens and found the student in the classroom. Police found a 9mm pistol with 13 rounds of ammunition in his backpack.

Jessica Tisch, the police chief of new york City, said that the students involved were controlled about 2 hours after they posted threat messages on campus, and no accidents occurred in the process.

New York Mayor Adams has criticized the fact that bringing minors so close to school shooting is an ¡°institutional failure.¡±
