A woman allegedly unleashed a barrage of antisemitic remarks before attacking a Jewish passenger on a crowded New York City subway Sunday, ripping out a chunk of the rider’s hair and shouting, “Jews are eating kids,” police said.

Authorities identified the suspect as Bronx resident Diana Smith, who allegedly made hateful comments about Jews aboard a C train traveling through lower Manhattan around 2:15 p.m. before confronting and assaulting a 23-year-old Jewish woman from the Upper West Side.

“I was a ragdoll and I couldn’t defend myself – there should have been a human barricade around me,” the Orthodox Jewish victim, who asked that her identity remain private, told The Post.

“No one stepped up until it was too late.”

The victim, a nurse originally from Montreal, said she entered the subway at Jay Street and was only traveling one stop when Smith boarded the train and began speaking to a couple about “the dangers of Jews stealing wealth.”

The woman then approached another couple and allegedly made another disturbing statement, saying, “You could always see the reflection of a Jew,” according to the victim.

“And then she turned towards me, like very targeted, stared me down, and smiled with this very eerie smile that I’ll never forget,” the Jewish woman said.

“I decided in that moment I really did not want to show fear in the face of that, so I stared at her right back down, and I said, ‘So you see my reflection?’ and she said, ‘Yeah, and I smell it on you too.’”

The victim recorded part of the confrontation on her phone, capturing Smith’s alleged antisemitic comments.

“Jews are eating kids,” Smith shouted.

The situation then turned violent, with Smith allegedly putting her hand on the victim’s throat.

Several passengers tried to intervene, while Smith allegedly yelled, “It’s OK for Jews to eat kids, but I can’t choke her down.”

Moments later, the victim’s phone was knocked away and Smith allegedly grabbed her by the throat, kicking and pushing her onto the subway floor, according to the woman.

The attack allegedly caused a clump of the victim’s hair to be ripped out.

When the train arrived at Canal Street, the Jewish passenger ran out to alert police while another rider pressed the emergency button, leading to Smith’s arrest.

“When I had to identify her, a ton of people were like, ‘Oh, we saw what happened, are you OK?’ And, that was extremely triggering for me, because, of course, I’m not OK. I kept just thinking, I’m not in Nazi Germany,” said the woman, who is 5-foot-3.

“How is this happening, and how is it that you saw what happened, and just were a bystander?”

The victim said she also sustained a concussion during the alleged assault.

Smith is facing charges including hate crime assault, hate crime criminal obstruction of breathing and aggravated harassment, according to court records.

“She’s pure evil, but she was lucid enough to know I was Jewish,” the victim said.

The attack occurred as the Israel Day Parade was taking place along Fifth Avenue in Manhattan, with Mayor Zohran Mamdani notably absent.

“I don’t think New York is protecting Jews. I don’t think Mamdani not going to the Israel Day Parade is helping,” the victim said.

The mayor has said he skipped the parade because he disagrees with the Israeli government, while also saying he intends to protect Jewish New Yorkers and support Jewish culture in other ways.

New York City has experienced an increase in antisemitic incidents since the Hamas Oct. 7, 2023 attack on Israel, which triggered the ongoing war in Gaza.
