BROOKLYN, N.Y. (WPIX) – Police in New York City have released new details about a shooting on a Brooklyn subway train that left one man in critical condition.

Police said Thursday that a 36-year-old man was shot in the head on a northbound A train near Hoyt-Schermerhorn station after he allegedly picked a fight with a subway rider at around 4:45 p.m. Authorities identified a 32-year-old man as the person who pulled the trigger.

Now, police say the 36-year-old man was also stabbed by a woman during the rush-hour chaos.

The woman, who was with the 32-year-old man when he allegedly shot the 36-year-old, was captured on video cutting the victim with a sharp object, NYPD Chief of Transit Michael Kemper said Friday.

It was unclear when during the incident the woman attacked the 36-year-old man, according to police.

“It’s a very active case,” Kemper said.

Authorities said Thursday that the victim is believed to have started the argument after the 32-year-old boarded the A train at the Nostrand Avenue station.

“This 36-year-old male was described by multiple witnesses as being aggressive and provocative toward the 32-year-old who just got on,” said Kemper.

Police said the 36-year-old pulled a gun on the 32-year-old, who disarmed him and shot him in the head.

The victim was still in critical condition as of Friday morning, police said. Cops quickly apprehended the alleged shooter at the scene; the 32-year-old was still in police custody Friday. It was unclear if he would be charged.

There may have been more than two dozen people on the train when the shooting occurred, according to Kemper. No other injuries were reported.

At Friday’s press conference, MTA Chief Janno Lieber thanked the NYPD for apprehending the alleged shooter and assisting at the scene.

“I’m here today to thank police officers who intervened and responded yesterday,” Lieber said Friday morning. “The cops went the extra step. As people were rushing up the stairs and rushing down the stairs, they made an immediate apprehension.”

The shooting happened just as the evening rush hour got underway. A and C trains were running with delays in both directions following the NYPD investigation at the Hoyt-Schermerhorn Streets station, according to the MTA. Service has since been restored.

Subway safety has been a key focus of Gov. Kathy Hochul and city authorities after a string of high-profile crimes, including back-to-back shootings on Bronx subways.
