CONCOURSE, the Bronx (PIX11) — A woman was attacked while aboard a southbound No. 4 train early Monday, police said.

Around 2:10 a.m., a 30-year-old woman got into an argument with a man. Things escalated when the unidentified man hit her with some sort of object, according to the police.

The woman got off at the 167th St. subway station then called the police. She refused medical attention at the scene, authorities said.

The suspect is described as standing around 6 feet to 6 feet, 2 inches and being of slim build with facial piercings, according to the NYPD.

This incident marks the seventh subway assault within the last 48 hours, following Mayor Eric Adams’ announcement of the city’s plan to make subways safer.

His plan involves sending more police, mental health clinicians and social service outreach workers into the subways. Adams spokesperson Fabien Levy said Monday that a “phased-in” implementation was beginning.

The plan notes that many people who use the subways for shelter need help, not handcuffs. But it says police will crack down on sleeping, littering, smoking, doing drugs or hanging out in the subway system.

“The facts of this weekend’s incidents make clear that each is a unique circumstance and shouldn’t be subject to sweeping generalizations,” Levy said. “We should not conflate such isolated acts of violence on the subways with broad statements about the behavioral and mental health challenges the city is confronting, or the issues of aiding those experiencing homelessness.”

Charleton D’Souza, president of Passengers United, considers the situation critical. He reiterated a call Monday night for a blanket-like NYPD presence in the subways.

“You have to walk the platforms. You have to walk up and down the mezzanines,” D’Souza said. “You just cannot sit by the turnstiles or sit in your patrol car, and that’s some of the stuff I’m seeing.”
