NEW YORK (CBSNewYork) — Two men were shot at a house party in Queens early Sunday morning, police said.

The shooting happened just after midnight at a home on 28th Avenue near 213th Street in Bayside, CBS2’s Ilana Gold reported.

A man and woman were arrested in front of the home later that day, but it was unclear as to why they were taken in, CBS2’s Matt Kozar reported. Neighbors said the woman lives at the home with her mother.

Authorities told CBS2 the home was being rented out for a birthday party. When the victims left, there was an argument, police said. Then a man walked up, opened fire and fled, cops said.

Sources say the owners rented out the house on the website AirBnb.

“You never see anybody in the front of the door, never,” Maria Zata, a neighbor, said.

Both victims were wounded in their torsos, according to police. A 27-year-old man is in crticial condition. A 23-year-old man is in stable condition.

It’s unclear what led up to the argument.

Police spent hours investigating, including questioning witnesses. They are still looking for the gunman and are asking anyone with information to contact them.

A neighbor said she thinks she knows why the shooting happened.

“Too many guns. Too many guns,” she said. “Look at that poor, innoocent cop, what happened to him.”

Up the street, another neighbor said there’s no simple way to get rid of guns.

“If you’re not able to buy one in the city, you’re going to go to another state, where it’s easy, and you’re going to bring it back,” she said.

Records on the real estate website Zillow show that the house sold in 2006 for $1.7 million.

It was a violent night across New York City. Seven people were shot and wounded overnight in six incidents in every borough but the Bronx, WCBS 880’s Marla Diamond reported.

Police said four of those shootings occurred in the span of an hour.

On South First Street in Williamsburg, Brooklyn, a woman was arrested for allegedly shooting her husband in the stomach.

In Far Rockaway, a woman was shot in the face by her husband, who fled the scene, police said.

Both wounded spouses are expected to survive.

A 37-year-old man was also shot in the leg in East Harlem, cops said.
