“Medics arrived and immediately provided medical treatment, but despite the efforts of the emergency responders the victim succumbed to his injuries and was declared deceased,” the spokesperson said.

Police said there is no evidence of foul play. The Office of the Chief Medical Examiner was called to the scene and that the investigation into the death is ongoing.

There were reports on Reddit that had witnesses saying the first person who fell from the upper level landed on his head with enough force to break the seat he struck. They also described staff trying to quickly clean up blood from the victim’s injuries as police proceeded to question concert attendees about the incident.

“It’s so lucky that nobody besides him was hurt,” the post read. “The sound and scene were incredible and horrifying.”
