The cause of the explosion has not been determined, said New York City police commissioner James O'Neill. The explosion, which seriously injured at least one person, happened on West 23rd Street late Saturday in an area frequented by shoppers and diners.
Another bomb was found nearby, apparently built inside a pressure cooker. This was safely removed by police.
New York Mayor Bill de Blasio said the blast was a deliberate act but said no links to terrorism had been identified.
Earlier in the day, an improvised explosive detonated in a rubbish bin in New Jersey, but did not cause any casualties.
Surveillance video recovered from West 23rd Street shows the explosion and contains other evidence that indicates to investigators the original object was intentionally left next to the construction trash container, described as 4 ft. by 4 ft. by 3 ft. in size. Officials said the NYPD has video it is reviewing and De Blasio urged any witnesses or people who may have information to come forward.
