A 34-year-old man was fatally stabbed during a massive brawl outside the victim’s Bronx apartment building early Tuesday, police said.

A second man, 32, was also stabbed during the fight, but is expected to survive.

Luis Almanzar was outside his apartment building on Marion Ave. near E. 188th St. in Fordham just before 12:30 a.m. when he and several others got into a fight with another group of men, witnesses told police.

Cops were called, but when they arrived Almanzar and the younger victim were the only ones at the scene. Both were bleeding from multiple stab wounds.

Almanzar, cops said, suffered stab wounds to his chest and right arm. The younger man had been stabbed repeatedly in the back, according to officials.

Medics rushed Almanzar to St. Barnabas Hospital, where he died from his wounds.

The other victim was taken to BronxCare Health System, where he’s expected to survive.

No arrests have been made.

Cops on Tuesday were scouring the area for surveillance footage that may help them track down those involved in the bloody fight.
