Federal officials are investigating the Nassau County Police Department after officers used a helicopter to try and disperse a group of around 500 teens who were on Jones Beach for “Senior Cut Day.”

Around 500 teens went to Jones Beach in Wantagh, New York, on Thursday after a flyer was spread on social media promoting “Senior Cut Day,” prompting the massive turnout. Witnesses told News 12 that the beach quickly spiraled out of control once the teenagers arrived.

A Nassau County Police Department helicopter was seen hovering over the large group of teens, lifting sand into the air as a result.

A spokesperson for the Federal Aviation Administration told Fox News Digital that the agency is investigating the Nassau County Police Department’s use of a helicopter in this situation.

Nassau County Executive Bruce Blakeman told Fox News Digital that the police’s actions saved others from getting hurt.

“We are confident that the actions taken by the NCPD aviation helicopter were instrumental in dispersing a large crowd of individuals who were engaged in fighting and other disruptive behaviors, thereby saving our kids from getting hurt.”

Police and other officials restricted access to areas of the beach to stop any continued violence on Thursday. No injuries were reported.

Officials allegedly saw multiple fights between the large group of teens.

“The beach was never like this,” said one person who saw the mass gathering of teenagers. “We came here as kids — it was so calm. But now it’s just crazy.”
