WCBS 880 reported the victim was with a group of three young men from the Washington, D.C., area.
“I don’t know what happened. I don’t know what happened,” one of the men told WCBS 880.
An eyewitness told CBS2 that a man was climbing a rock structure and stepped on something that “exploded.”
A senior law enforcement official told NBC 4 New York that preliminary information suggests that the explosion was a firework accident that led to a significant foot injury, possibly an amputation.
The official also said friends of injured man deny they were playing with fireworks, so the NYPD bomb squad is investigating to determine what the material is that caused the injury.
