BROOKLYN, N.Y. – A straphanger apparently angry over access to a subway pole lunged at her fellow riders while wielding a sharp object and threatening to cut them and “get away with it,” in a caught-on-camera confrontation, authorities said Tuesday.

It went down about 7 p.m. Dec. 18 on a downtown A train as it approached the Jay Street Metro-Tech station, police said.

In a video obtained by Gothamist, the attacker is seen repeatedly approaching the victims, even after they’ve stopped arguing with her. The outlet reports the fight began over a pole in the train car that the attacker was leaning on.

“Do you want to see what happens when I get off this train?” she said. “I’m going to cut you and I’m going to get away with it.”

The culprit ordered the victim to be quiet and told him, “You can talk when I get off this train.”

But when he began conversing with another person on the train, she erupted, grabbing a sharp object from her bag and lunging toward the man.

Victim: “You have a knife!”

Attacker: “Yeah, I do.”

The victims – a 28-year-old woman and a 48-year-old man – suffered cuts to their faces and heads and exited the train at Nostrand Avenue, police said. The pair refused medical attention while their attacker ran from the scene.

The culprit is described as a black female about 30 years old standing 6 feet tall and weighing about 180 pounds, police said. She had black hair and was last seen wearing a black sheer blouse, black pants, black shoes, yellow coat and carrying a red purse.

Any witnesses who were on the train that night or anyone who recognizes the attacker are urged to call Crime stoppers at 1-800-577-TIPS (8477).
