"Clearly, I would say that this is somebody that had knowledge of chemistry.... This is clearly explosive material. But there's nothing to indicate that this was an explosive device that was placed or put in this area with a specific intent to harm any individuals."NYPD Deputy Chief John O'Connell said:
"We do not have any evidence of a constructed device or commercial-grade fireworks. There are no specific, credible threats directed at New York or the July Fourth celebrations."
