NEW YORK (WABC) -- Video captured from a passenger's phone shows the moments that escalated to a shooting on a subway train in Brooklyn that sent riders running for their lives.
The incident unfolded on a northbound A train at the Hoyt-Schermerhorn station around 4:45 p.m. Thursday.
One man was hospitalized in critical condition, one man is in police custody and one woman is still being sought by police.
Charges are now pending against a 32-year-old man who police say shot a 36-year-old man during the dispute that was captured on camera.

The video shows a verbal fight broke out between the two. It appears the 32-year-old man boarded the train and was approached by the 36-year-old.
It was later determined a third person, a woman with the 32-year-old, was also involved. The cellphone video appears to show her stabbing the 36-year-old in the back.
Authorities say that after he was stabbed, the 36-year-old man asked "Did you stab me?" He pulled a gun from his jacket and asked again, "You stabbed me, right?"
The 32-year-old man was able to grab the gun before multiple shots were fired. The 36-year-old was taken to the hospital where he is said to be critical but stable.
The terrifying passenger video shows the panic that broke out among the others on the train as people hovered together for safety.
Many begged to be let out before the doors opened and they ran for their lives. Some passengers were trampled and many were left traumatized.
According to the MTA, if there is an immediate threat in your subway car, move to another car. And if your subway car is not equipped with an intercom, alert the conductor in the middle of the train at the next station by waving or vocalizing when doors open.
A passenger who wanted to be identified as Ms. Paul was one of the riders who scrambled to escape the chaos.
"It's something you don't want to ever experience in your life," she said. "When I flew, everybody followed me and went on top of me."
The mother of five was just trying to get back to her home in Brooklyn. She said the door leading to the next train car wouldn't open, so she was left waiting for the train to stop. And as it did, the gunshots rang out.
Former federal agent and security expert David Katz said there is one thing to do if you are paying attention before a conflict escalates.
"If someone comes to your attention - like I'm not sure about this person - either get off and on a different car, or maybe now is not a time to return emails," Katz said.
Ms. Paul said she no longer feels safe using the subway anymore and she doesn't even want to stay in New York.
