NYC Subway Violence, Deaths in 2013: Attacks Continue as Two Police Officers Are Shot on Train in New York City, One Suspect Killed

Are New York City subways getting more dangerous?

Two police officers were shot on a train on Thursday, and one suspect who exchanged fire with police was killed. A bystander was also grazed by a bullet.

At 7:30 p.m. two plainclothes police officers, Michael Levay and Lukasz Kozicki, stopped a man who crossed between subway cars. When they asked him for his identification, he "pulled a 9-millimeter Taurus handgun from his waistband and opened fire," according to New York City police commissioner Raymond Kelly.

Kozicki was hit once in each thigh and once in the groin. Levay was hit in the lower back, but his bulletproof vest stopped the bullet. He returned fire, killing the man, whose name has not been released, but Kelly said he had been arrested at least five times, once for assault with a knife.

The shootings come just a few days after a woman stumbled onto the subway tracks near Times Square and was killed by an oncoming train in the early morning hours of New Year's Day.

On New Year's Eve, a fare jumper attacked and choked an officer who was trying to arrest him near Times Square.

And in December, two separate pushing deaths made headlines.

Naeem Davis pushed Ki-Suk Han after an altercation near Times Square in early December. Han tumbled onto the tracks and was hit by a train and died.

Just a few weeks later, Erika Menendez pushed Sunando Sen in front of a train in Queens after mistaking the Hindu man for a Muslim in a murder classified as a hate crime.
