NYPD cops who were monitoring a Queens house party Friday night shot three males after the group rolled up and opened fire on the 75 to 100 partygoers, according to police.

The violence erupted about 11:35 p.m. Friday night at Springfield Boulevard and 130th Avenue in Laurelton and sent the three alleged shooters to the hospital with injuries, NYPD’s Chief of Patrol Jeff Maddrey said.

The plain-clothes officers in unmarked vehicles were watching the party because they feared there was a “potential for violence by some of the local street crews,” police said.

The melee began when plain-clothes officers spotted a group of men show up to the party, threaten revelers with guns and open fire.

As a number of party attendees shot back, the cops drew their weapons and fired at the gunmen, according to sources.

Maddey said no officers were injured in the exchange of gunfire.

Two of the alleged shooters suffered non-life threatening injuries, the third suspect is in critical condition. 

Police recovered three firearms from the scene.

The investigation continues and cops are seeking information from the “large number of people” who were at the party.

Anyone with information is urged to call Crime Stoppers: 800-577-TIPS.
