Three devices found in New Jersey and two in New York have used cell phones as detonators

The pipe bombs in New Jersey used flip phone timers and as did pressure-cooker device found in Chelsea

It's believed home-made bomb that exploded also used old-school flip phone as a detonator

Another similarity is lack of know-how that went into making the devices as three failed to detonate

Believed that the metal dumpster the bomb was placed in prevented loss of life in Manhattan

CNN have obtained video that shows the same man at 23rd and 27th streets - where the bombs were left

Another two men are seen on video removing the pressure cooker from a duffel bag on 27th

Authorities aren't able to say if the New Jersey bombs are related to the explosion and device in New York

Currently, there the incidents don't appear related but de Blasio isn't 'taking any options off the table'

Three pipe bombs found in New Jersey and two IEDs that terrorized New York City on Saturday all have one thing in common - cell phones.

An old-school flip phone was used as a timer in all five home-made bombs.

Authorities said they still have not found any indication the incidents in New Jersey and New York are related, but in both cases flip phones were used as timers to detonate the explosives.

All phones used as detonators were similar in design, according to PIX 11.

And this comes as CNN claimed to have seen video which places the same man at 23rd and 27th streets in Manhattan - where one bomb detonated and another pressure cooker device failed to detonate.

The security footage from Saturday reveals a man dragging what appears to be a duffel bag on wheels near to the bomb detonated on 23rd street. This was 40 minutes before the blast

Another video also appears to show the same duffel bag on 27th street.

In this video, the man seen at both locations leaves it and then two men approach the bag and remove a white garbage bag.

It is not know if the two men are connected with the individual seen at both locations.

'We don't have everything in. Think of a jigsaw puzzle out in the street right now,' said NYPD Chief of Detectives Robert Boyce. 'Do we think they're related? Yes, we have to move in that direction, but right now we're not ready to make those calls yet.'

The explosions happened on the same day a pipe bomb went off near a Marine Corps charity run in New Jersey and nine people were stabbed by a man at Minnesota mall - leading some to say America underwent three terror attacks in the space of 12 hours.

We do not have any specific evidence of a connection, but that will continue to be considered. We're not taking any options off the table,' New York City Mayor Bill de Blasio said.

Investigators told NBC 4 New York all the old-fashioned flip phones were found attached to the devices.

Authorities have also said another similarity was the lack of know-how that went in to making the bombs.

Out of the five devices found or detonated on Saturday, three failed to work as designed.

An undetonated pressure-cooker explosive had a cell phone attached to it and New York Governor Andrew Cuomo said the device was similar to the one that exploded in the Manhattan neighborhood of Chelsea.

Additionally, the devices found in New Jersey contained an easily obtainable explosive black powder.

Residue of an explosive often used for target practice that can be picked up in many sporting goods stores was also found in the Manhattan bombing, a federal law enforcement official said Sunday.
