A good Samaritan jumped into action when he saw a car sinking in the Newark Bay with the driver trapped inside.

The lifeguard and swim instructor saw the SUV quickly sinking just yards from the shore.

"The car is way out in the water, with the man out the window. He is yelling something and the car is going down," said Bayonne resident Helena Bilodeau.

As the crowd grew and commotion got louder, it caught the ear of Anthony Capuano.

"I saw people running and we did the same," Capuano said.
