NEW YORK — New York City police say they've uncovered traces of substances common in explosives in a device that detonated when a college student stepped on it in Central Park, resulting in the amputation of part of his leg.
Connor Golden, a University of Miami student from Fairfax, Virginia, was at the park July 3 with friends when he stepped on a rock covering the explosive. He lost his lower left leg and foot.
Investigators don't believe the device was meant to intentionally hurt anyone.
Police said Thursday the substances found in the investigation are legally available in hardware stores and can be used with other products to develop homemade explosive devices. Investigators say they believe the explosive was made by someone experimenting with commercially available products.
It specifically was the homemade explosive TATP, law enforcement officials told CNN. The chemicals used to make the explosive were put in a shopping bag. The bag was pressure sensitive and was activated when Golden put his foot on it.
TATP has been used in terrorist attacks for decades, including last fall's Paris attacks.
Golden had a second surgery "due to complications from what doctors describe as a local infection in the area of his wound," and he's still at Bellevue Hospital. Friends of Golden started a GoFundMe page last week.
