Investigation underway into NYC explosion that injured 29

“There’s no specific and credible threat against New York City at this time from any terror organization, he said”.

Associated Press writer Eric Tucker in Washington contributed to this report.

After an initial news conference, a second device believed to be a pressure cooker was found on West 27th Street, four blocks from the initial blast on West 23rd, according to New York Police Department.

He added that the site of the explosion, outside on a major thoroughfare in one of the most bustling areas of New York City, was being treated as a crime scene.

City officials also declined from commenting whether there is any link with the explosion of a device in Seaside Park in the neighboring state of New Jersey, where no victims or material damage was reported.

New York City Mayor Bill de Blasio said then that it was “too early to determine specifically what the incident was caused by” and that the investigation was still underway.

New York City Police issued a bulletin advising motorists that they should “expect extensive traffic delays and emergency personnel in the area” due to police activity.

Mayor Bill de Blasio called the explosion – which occurred about 8:30 p.m. on West 23rd Street – “an intentional act” but initially said there was no connection to terrorism and no immediate claim of responsibility.

Cuomo said Sunday that all the injured who were taken to a hospital after the blast had been released.

Gov. Andrew Cuomo, who toured the site of the blast in Manhattan’s Chelsea neighborhood, said there didn’t appear to be any link to worldwide terrorism.

As a precaution, the police and fire personnel searched for additional devices but found none, officials said.

CNN law enforcement analyst Tom Fuentes said the information authorities have revealed so far about the blast leads him to a troubling conclusion.

De Blasio tried to calm any fears among nervous New Yorkers, saying the explosion had no terrorist connection and wasn’t related to a pipe bomb explosion earlier Saturday in New Jersey that forced the cancellation of a charity run.

The explosion rocked Chelsea, a NY neighborhood that’s packed with restaurants, subway stations, shops, businesses and art galleries.

“I feel a little bit insecure, but we have to do what we have to do”, said Omar León, a real estate investor who was visiting a friend on Saturday night in the building directly next to the blast site. Eyewitnesses have said that windows were shaken and broken by the blast and debris was scattered onto the street.

Investigators are still searching the scene for evidence, officials said.
