NYPD officers from the 10th Precinct saw the incident while on routine patrol.
The site of the blast is being treated as a crime scene. The investigation into the incident is ongoing.
Cause of the blast
NYPD Police Commissioner James P. O'Neill said that the exact cause and the nature of the explosion have not been determined.
The NYPD Bomb Squad and the FBI Joint Terrorism Task Force were requested at the scene, fueling concerns that officials have not ruled our terrorism as a possible cause of the blast. Mayor de Blasio said that there was "no evidence at this point of a terror connection."
Other suspicious devices
Investigators found a second device that appeared to be a pressure cooker attached to wiring and a cellphone wrapped in a plastic bag on West 27th Street. It has been taken to a firing range in the Bronx.

Republican presidential nominee Donald Trump was one of the first to comment on the explosion in Chelsea. "I must tell you that just before I got off the plane a bomb went off in New York and nobody knows what's going on," he said at approximately 9:10 p.m.
"But boy we are living in a time… We better get very tough, folks. We better get very, very tough. It's a terrible thing that's going on in our world, in our country and we are going to get tough and smart and vigilant," he said.
Democratic hopeful Hillary Clinton said that the US needs to support its first responders and "pray for the victims," adding that "we have to let this investigation unfold."
