NEW YORK (CBSNewYork) – One man is dead and a convenience store employee was charged with murder after an incident in Harlem Friday morning.

Ahmed Hafeed, 22, has been charged with second degree murder and manslaughter.

The incident took place on West 145th Street and Lenox Avenue just before 9:30 a.m.

A 46-year-old man apparently walked into the store with a knife and an argument broke out, CBS2’s Marc Liverman reported. The fight continued into the street, and ended with a man bleeding out a half block away.

“He was in pain. The knife stabbed his stomach. He was losing blood,” Laverne Allen said.

Witnesses told Liverman that the man attempted to rob the store, though police have not confirmed that.

Hafeed struggled with the man, and the 46-year-old was stabbed in the stomach.

He staggered down the street and collapsed at a nearby Dunkin’ Donuts, Liverman reported.

“He took the knife and threw it behind the garbage can at Dunkin’ Donuts and he collapsed,” Allen told 1010 WINS’ Juliet Papa.

He was rushed to a nearby hospital but died.

A witness told Liverman the worker stabbed the man “in self defense” after the struggle.

“With the perp’s own weapon, because the owner was about to get hit by a bus. They was tussling on a curb, and somehow he got free. I guess he had the perp’s weapon and stabbed him self-defense, because he had bruises from fighting,’ Jason Hayes said.

Police told CBS2 that the man was stabbed over and over again and somehow ended up at the Dunkin Donuts.

Another witness, who runs the deli across the street, said the worker ran into his store and told him to call 911.

“He was filled with blood, I saw a thin wound on his hand,” the witness told 1010 WINS’ Juliet Papa.

Hafeed was questioned following the incident, and later charged. The knife was recovered.

Another store employee told Liverman there have been about 10 fights at the store in the past seven years.
