Two people were taken to a hospital in serious condition after a shooting at a Bedford-Stuyvesant subway station Tuesday that caused disruptions in train service.
Officials said someone fired a gun in a the stairway leading to the Utica Avenue station shortly after 5 p.m.
The sound of gunfire sent commuters running.
"It sounded like one gun, it wasn't a shootout," said Chaka Parker, who was walking out of a store near the stop. "Anybody could have gotten shot. You didn't know where it was coming from, who was shooting."
Moments later, she said she watched two men being helped by first responders and heard a victim crying out in pain.
"I heard him yelling, his stomach, his stomach, and he was holding his stomach," she said.
Community activist Tony Herbert said the shooting may have stemmed from a dispute between the gunman and one of the victims, but it's not clear if they knew each other.
"He pulled a gun, chased an individual down the subway steps and shot at him," he said.
The gunman is being sought by police. Sources on the scene said they're looking for a man in a gray hooded sweatshirt captured on surveillance video.
The victims were both taken to the hospital; at least one of them is expected to survive, authorities said.
