Four people were stabbed after a holiday party turned violent in The Bronx on Christmas morning, police said.

Revelers were drinking at a house party on East 165th Street in Concourse Village when a fight broke out at around 5:50 a.m., leaving four — ages 21, 24, 29 and 35 — with stab wounds, cops said.

The victims were taken to Lincoln Hospital with non-life threatening injuries.

It was unclear what sparked the incident, police said, and the victims were uncooperative. There were no immediate arrests.
