A 21-year-old Poughkeepsie man was stabbed outside a Coram house party early Sunday morning, police said.

The man, who was stabbed in the abdomen and arm, sustained non-life-threatening injuries, Suffolk police said.

The man had been a guest at the party on Canterbury Lane organized by a 22-year-old woman and publicized on social media sites, police said.

Sixth Precinct police officers had responded to the residence on Saturday about 11:20 p.m. after receiving complaints about loud music, police said.

The officers dispersed the crowd and calmed the disturbance. But about 1:15 a.m. on Sunday, a crowd of more than 200 people grew beyond the hostess’ expectations and became disorderly, police said.

The stabbing victim attempted to control the crowd when he was confronted by a male partygoer, police said. The verbal dispute escalated into a fight, during which the victim was stabbed in the abdomen and left arm, police said.

The suspect is described as a man his early 20s with braided hair. He was wearing jeans and a plaid shirt.

An investigation into the stabbing is a joint operation between the Sixth Squad and the Sixth Precinct Crime Section, whose officers will investigate possible violation of the Suffolk County Social Host Law, police said.

Police said two other arrests, which were not related to the assault, were made at the residence: A 19-year-old Miller Place man was charged with marijuana possession, and a 21-year-old Mastic Beach man was charged with second-degree harassment after he physically harassed a police officer, police said.

Anyone with information about the stabbing or the party can call Sixth Squad detectives at 631-854-8652 or Crime Stoppers at 800-220-8477.
