This is the moment the Port Authority bomber detonated his home-made explosive — and heroic NYPD cops rushed into danger to arrest him.
Newly released video obtained by NBC News for the first time shows the dramatic aftermath of the attempted rush-hour suicide attack on Dec. 11 — which mercifully misfired and failed to kill anyone, including alleged bomber Akayed Ullah.
After the pipe bomb goes off and the attacker falls to the ground — and a nonchalant subway cleaner arrives to sweep of some detritus the footage shows New York’s Finest swooping in and surrounding the seemingly lifeless body.
Then, the bomber’s leg suddenly twitches, and the cops fall back as he writhes around on the ground.
A handful of officers then cautiously return — but as soon as the attacker reaches for what appears to be his cell phone, they pounce, securing his arms and slapping on cuffs.
Officers Jack Collins, Sean Gallagher, Drew Preston and Anthony Manferdini have been hailed as the brave cops who made the final arrest.
Manferdini is a former Marine with bomb technician experience, Gallagher is an ex-Marine and Preston served as an Army solider.
