A man suffered serious injuries Sunday due to an explosion in New York's Central Park, according to multiple reports.
The victim's leg was injured while he climbed a rock and stepped on something that "exploded" near the corner of 5th Avenue and 68th Street just before 11 a.m.
Police are pointing to a fireworks mishap as the likely cause, according to CBS New York.
An FDNY spokesperson said it is a major injury and that it may involve a possible amputation.
As the victim was rushed to a nearby hospital, NYPD began investigating what it was that exploded. A bomb-sniffing dog was seen entering rock area where the explosion took place.

Authorities closed off a section of Central Park near the Central Park Zoo as they work to verify the cause of the accident.
Twitter user and former New York Times colunist Sarah Maslin Nir described what she heard and saw, tweeting:
"Outside Eli Wiesel's funeral I heard a huge explosion just now. Running into Central Park and found a young man with his left leg blown off."
While many reports and the time of years pointed to fireworks as the possible cause, investigators had not officially revealed what led to the explosion as of early Sunday afternoon.
