An explosion from a suspected bomb in a trashcan ripped through Manhattan on Saturday night leaving at least 29 people injured - and police are investigating a second suspected bomb in a pressure cooker.

Terrifying CCTV footage shows the blast ripping through New York's affluent Chelsea neighborhood at around 8.30pm on Saturday night.

The Office of the Deputy Commissioner Public Information (DCPI) exclusively told DailyMail.com the video was 'confirmed amateur video footage from incident location'.

The blast on 23rd Street and Sixth Avenue is believed to have come from a dumpster and was the result of 'an intentional act', according to the NYPD.

Although Mayor Bill de Blasio has claimed there's no connection to terrorism, the incident follows the pipe bombing of a military fun-run in New Jersey hours earlier. No one was injured in that attack.

De Blasio also admitted the explosion was 'intentionally' set off, suggesting the intent was to injure people in an attack on Manhattan. All the victims including an eight-year-old boy have minor injuries, except one who is in critical condition.

The second device at 27th Street and Sixth Avenue, which was removed by the NYPD early on Sunday morning, is in a pressure cooker - raising chilling memories of the Boston bombings in 2013.

The pressure cooker has different colored wires sticking out of it and is wrapped in a plastic bag with what appears to be a cell phone or timer connected to it.

The pressure cooker was also reported to be wrapped in duct tape with a note attached to it.

Investigators have now said they are reviewing surveillance footage that shows a person standing near the site of the first explosion shortly before the blast.

Hundreds of people fled the scene after the blast, and witnesses described the harrowing incident as they were enjoying a night out in the city.

'I was eating at the restaurant Mira with my family and we heard a huge noise and the entire restaurant shook,' Emily Brookstein, 30, of New York told Daily Mail Online.

'My dad thought it was thunder but we obviously realized later that wasn't the case. We came out of the restaurant and could see smoke. Some say it was a subway bomb, but it was definitely an explosion.'

'It was really loud, it hurt my eardrums. My 10-year-old boy was sat in the back seat of the car, and the explosion blew the back window out,' said Tsi Tsi Mallett, who was in a car driving along 23rd Street when the explosion took place.

Her son was not injured.

Simitrio Ramirez, 53, who lives nearby in the area said he was home when he felt the explosion.

'With construction in the area, I thought something big fell,' he told Daily Mail Online.

He said he could feel his apartment shake when the explosion happened. A witness who did not want to be identified was with friends in an apartment nearby when he said they could feel the windows cave in.

An officer told Daily Mail Online that they blocked off the area two blocks north and two blocks south of Sixth Avenue and 23rd Street.

Police believe the blast was a homemade bomb placed in the trashcan.

A DailyMail.com photographer reported hearing a 'bang' at the second site where the pressure cooker was found, suggesting authorities may have conducted a controlled explosion.

By 2.30am the NYPD tweeted that the second device had been safely removed from the area by the Bomb Squad.

The victims of the explosion were taken to several different hospitals.

De Blasio said during a press conference that injuries 'are significant but at this point we can confirm that none of those injured are likely to die'.

'There is no evidence at this point of a terror connection.' De Blasio also said it is 'too early to determine' if the incident in New York is connected to the explosion in New Jersey.

However, the mayor said: 'We believe that it was an intentional act.'

He added that investigators are tracing every lead but it's still too early to give any details of the investigation.

De Blasio urged witnesses who took video of the blast to send them to the NYPD.

At the time, she was walking to the Michael Kors store and was near the 23rd Street Station on 5th Ave when the explosion occurred.

She said it sounded like a bomb.

The explosion in the Chelsea neighborhood comes just hours after the deadly pipe bomb that exploded along a route where thousands of runners were due to take part in a charity run in New Jersey

Magnani said she is in New York on holiday and is staying at the Heritage Hotel.

'I was really scared I immediately called my family,' she said.

More than one thousand spectators, including war veterans and small children, had gathered just a few blocks from the blast in Jersey Shore town on Saturday afternoon.

Two more pipe bombs, that hadn't exploded, were found in a garbage can near the event which sought to raise money for marines and sailors.

The pipe bomb near D Street exploded about 9.30am - the exact time runners were due to pass that location.

No injuries were reported but bomb-sniffing dogs have continued to look for more bombs in the area.

Explosive experts in New York will be comparing the Manhattan explosion to the New Jersey incident to see if the two have anything in common.
