An explosion in New York City's Central Park left a man severely injured.
Eighteen-year-old Connor Golden from Fairfax, Virginia, was walking with two of his friends not far from the Central Park Zoo when the explosion occurred.
A New York City Fire Department spokesperson said Golden was taken to a hospital for "possible amputation."
According to witnesses, Golden stepped on something that blew up, severing one of his feet.
"I have no idea what it was. It sounded like a cannon. So that's why I thought it was like a Fourth of July thing," one witness told CNN.
Police say they aren't sure what caused the explosion, but they speculate that it could be fireworks since Monday is the Fourth of July.
