The NYPD on Thursday asked subway riders who witnessed another passenger choking a homeless man to death on an F train earlier this week to come forward with information about the incident.

In a statement, the NYPD said it was urging anyone with information related to Jordan Neely's death to contact its Crime Stoppers unit "in an attempt to identify and interview as many witnesses as possible."

"As part of the ongoing investigation into this tragic incident, NYPD detectives are actively reviewing footage and all other available information," the department said. "The New York City Police Department's first priority is always to seek justice."

"The NYPD continues to work closely with investigators at the Office of the Manhattan District Attorney," it added.

Jordan Neely, 30, died Monday of compression to the neck, the city medical examiner's office said. The Manhattan district attorney's office is investigating the incident.

Video taken by a bystander showed another man putting Neely in a chokehold on a northbound F train as it pulled into the Broadway-Lafayette station in Manhattan Monday afternoon.

The NYPD on Thursday said its officers found Neely unconscious on the floor of the train around 2:30 p.m. He received aid from police officers and EMTs but was ultimately pronounced dead at Lenox Hill Hospital, police said.

The 24-year-old man who was seen in the video choking Neely was taken in by police and released without charges, according to the NYPD.

The NYPD said early Wednesday that officials were waiting for the medical examiner's report to see whether the case needed further investigation or to bring the man back into custody. On Wednesday evening, the medical examiner ruled Neely's death a homicide.

Witness Juan Alberto Vazquez uploaded a video on Facebook with a post that said Neely was yelling in the subway car that he had no food or anything to drink, that he didn't mind going to jail and getting life in prison, and that he was "ready to die."

Vazquez wrote that Neely threw his jacket to the ground aggressively.

That's when the 24-year-old man put Neely in a chokehold, the video shows. Another man can be seen holding Neely's arms down.

The NYPD said Neely was known to them as a man with more than 40 arrests, though officials did not say for what.

To those who came to a vigil at the Broadway-Lafayette station on Wednesday, he was a man who delighted subway riders busking as a Michael Jackson impersonator.

Gov. Kathy Hochul weighed in initially on Wednesday, saying, "People who are homeless in our subways, many of them in the throes of mental health episodes, and that's what I believe were some of the factors involved here. There's consequences for behavior."

Hochul was asked about the incident again Thursday. She called the response of the men on the subway "extreme" and expressed sympathy for the victim's family.

"I do want to acknowledge how horrific it was to view a video of Jordan Neely being killed for being a passenger on our subway trains. And so our hearts go out to his family," she said. "I'm really pleased that the district attorney is looking into this matter. As I said, there had to be consequences, and so we'll see how this unfolds. But his family deserves justice."

Mayor Eric Adams issued an initial statement in response to the incident Wednesday, saying: "Any loss of life is tragic."

"There's a lot we don't know about what happened here, so I'm going to refrain from commenting further. However, we do know that there were serious mental health issues in play here, which is why our administration has made record investments in providing care to those who need it and getting people off the streets and the subways, and out of dangerous situations," he said. "And I need all elected officials and advocacy groups to join us in prioritizing getting people the care they need and not just allowing them to languish.
