A woman was shot in the gut early Saturday as she walked through a a pitch-black train underpass in East Harlem, police said.

The 29-year-old was walking with a friend around 2:30 a.m along East 107th Street and Park Avenue, when she was shot in the stomach, officials said.

“A lady was on the phone. She was calling 911,” said Terrence Truitt, 35, whose building faces the Metro-North train tracks.

“I couldn’t hear everything she was saying because it was garbled, she was frantic. I heard, ‘Gun shots!’ ‘Come quickly!’ ‘I need help!’”

The victim was taken to Mount Sinai St. Luke’s hospital in stable condition, authorities said.

Residents said the tunnel attracts crime because it’s poorly lit. “It’s not safe to walk through there at nights,” one East Harlem dad said.

“We just have to be careful, keep our eyes open, always looking around us,” he said, spinning his head around. “Make it quick, don’t linger. I have two little girls, and I don’t want anything happening to them.”
