NEW YORK (CBSNewYork) – Police were searching late Tuesday for a well-dressed woman who was caught on video proclaiming that she going to “cut” someone and “get away with it” – and allegedly went on to slash two people on a Brooklyn subway train.

As CBS2’s Dave Carlin reported, smartphone video showed the stylish suspect riding an A Train around 7 p.m. Friday near the Jay Street-MetroTech station. She is seen wearing a yellow tailored coat, accessorized with a big red bag, movie star sunglasses — and a razor that it turns out she is not afraid to use.

“This is going to end very badly,” the woman said.

WARNING: This video contains some foul language and violence.

The two-minute, 15-second video does not show the beginning of a conversation that turned into a quarrel between the suspect and a 28-year-old woman and a 48-year-old man she did not know.

But it took a sudden violent turn between Jay Street and Nostrand Avenue.

“Do you want to see what’s going to happen when I get off this train?” she says. “I’m going to cut you. And I’m going to get away with it. Now if you say one more word, it’s going to end very badly. Do you understand?”

She then approaches the two victims and waves the object in their faces, asking again “Do you understand?”

The woman then continues to approach the two, telling them repeatedly to shut up. The man tells her to stop following him.

“I’m f—ing crazy,” the suspect says.

When the woman notices someone is making a video of the incident, she waves to the camera, says “Hi, I’m used to cameras,” and then blows a kiss. “Make sure you get my good side,” she says.

A few moments later, the suspect lunges at the man, attacking him, saying “You really want it?”

Both victims suffered small cuts on their faces, police said. They refused medical attention.

The woman got off at Norstrand Avenue, police said.

“Oh my God, that is – that’s unbelievable,” said Roxanne Lewis of Far Rockaway, Queens.

Subway riders, who said they have seen a lot of unpleasant things on trains, found it chilling that the suspect appeared to jab at the victim, stop to pose for the camera, and then return to violence that got worse as other riders tried and failed to restrain her.

“I already think the subway scary, but that’s especially scary, because it’s not who you would expect,” one woman said.

“She looked like she was normal; like she was checking something out in her bag,” added Lewis. “There’s a snap — you can see it, like she got attitude.”

“She looks like a normal, everyday person — but people like that normally do,” added Debra Wheeler of East New York, Brooklyn.

“It shows me you got to be cautious with any confrontation you have with anyone on the train or anything like that,” said Carlos Tam of Bedford-Stuyvesant, Brooklyn.

Police describe the suspect as black, approximately 30 years old, 6’0” tall, 180 pounds with black hair. She was last seen wearing a black sheer blouse, black pants, black shoes, a yellow coat and carrying a red purse.
