A pressure cooker was discovered, as reported by the Inquisitr, on 27th Street. It was not known if the pressure cooker was an actual IED or something merely fashioned to appear dangerous.

Meanwhile, the security footage video from Orangetheory Fitness Chelsea center shows two different vantage points of the explosion that rocked the Chelsea neighborhood in Manhattan on Saturday evening that hurt at least 29 people.

Now called an "intentional act," the explosion caused people to flee outside of the Orangetheory Fitness Chelsea location, as folks who were previously strolling casually down the Chelsea neighborhood street began to run in fear.

The inside view of the Orangetheory Fitness Chelsea security video showed debris raining down inside the Orangetheory Fitness Chelsea center, as the blast could reportedly be heard and felt from far away. The Orangetheory Fitness Chelsea video showed the damage and reverberation caused by the explosion. The video does not appear to have audio attached to the visual aspects of the footage.

Thus far, authorities have said there is not evidence of a terrorist connection for the Chelsea blast.

The discovery of the pressure cooker on 27th Street caused authorities to warn some Chelsea residents to stay away from their windows as they dealt with the removal of the device.
