A Borough Park man was slashed to death last night during a fight outside his home, cops said.

The victim, Obedo Tum, 28, had some people over to his apartment on 40th Street near 13th Avenue, said police sources.

An argument broke out while the group was drinking. The brawl spilled outside, and Tum was stabbed once in the stomach at about 11:30 p.m., sources said.

Tum was pronounced dead at the scene.

It was not immediately clear what the fight was over, and no arrests have been made.
