Man arrested in stabbing on B’klyn subway

Hate crime detectives busted a Queens resident in the possibly bias-fueled stabbing of an Asian man on a Brooklyn subway train, police said.

Nicholas Martin, 24, was charged with assault and assault as a hate crime after he surrendered to cops at the 105th Precinct in Queens, police said.

The 39-year-old victim first got into an argument with three kids on the F train platform at the East Broadway station on the Lower East Side at about 2:55 p.m., cops said. He then stepped onto a Brooklyn-bound train, where he got into an argument with Martin, said police.

Both men uttered racial slurs, and at some point during the ride Martin whipped a knife out of his backpack and slashed the victim in the chest and back of his neck, police said.

The victim was treated at Brooklyn Hospital and is recovering, cops said.

Martin ran off the train when it stopped at the York St. station near Jay St. in downtown Brooklyn.

He surrendered to police on Thursday, just a few hours after the Daily News and other outlets published MTA surveillance photos of him leaving the station.

His arraignment at Brooklyn Criminal Court was pending Friday.

Tuesday’s attack was one of two stabbings in less than 24 hours in the city’s subway system. Both incidents are suspected of being hate crimes.

In the second incident, an assailant used anti-gay slurs when he stabbed a stranger on a Bronx subway train for playing music too loud about 1 a.m. Wednesday — and then changed his clothes as he fled to avoid being caught, police said Thursday. No arrests have been made in that case.

The city has seen a 13% increase in assaults in the subway so far this year. As of May 29, 250 assaults had been investigated by Transit Bureau police officers — 30 more than the same time last year.
