Woman fatally stabbed protecting beau during wild NYC nightclub brawl

A 35-year-old woman was slashed to death with a broken bottle while trying to protect her beau from a deranged mob during a massive caught-on-video Sunday morning brawl outside a Bronx nightclub.

The mayhem erupted shortly after 4 a.m. outside the Mama Dora club on East Kingsbridge Road when a fight began between two groups as the bar emptied out, law-enforcement sources and witnesses told The Post.

With fists flying, one combatant — identified by locals as the woman’s husband — hit the ground, prompting her to step in to try to protect him from his attacker, according to witnesses.

That’s when she was stabbed — with the fatal melee caught on surveillance footage.

What appeared to be a woman’s hair extension was left behind on the sidewalk, along with shattered glass.

“They were fighting, and they were all outside,” a man who witnessed the brawl said. “[The victim] came out with her husband, then the other guys came out, too

“That’s when the two groups got into a fight,” said the witness, who asked not to be identified. “She got in the middle so they wouldn’t get to her husband, and that’s when she got stabbed.”

Another bystander said the culprit used a shattered bottle to deliver the death blow before the group fled the scene — with no arrests as of Sunday afternoon, even as shattered glass still littered the sidewalk.

Police said the slain victim, who is not being identified, suffered “multiple stab wounds” to the chest.

She was put into a private vehicle and rushed to BronxCare Health Systems and then transferred to Lincoln Hospital, where she was pronounced dead, according to police.

Surveillance footage from a nearby business captured much of the mayhem.

The dramatic clip shows a man wearing a yellow jacket jumping about excitedly, then lunging forward and stabbing the woman before he appears to be whisked away by his pals.

A witness to the scene said the bloody attack left him speechless.

“There’s not much left in the world,” he said. “I have nothing else to say. They need to find God.”
