#Man stabs ex-girlfriend’s new beau inside Brooklyn apartment

An enraged ex-boyfriend stabbed his former flame’s current beau during a scuffle in a Brooklyn apartment early Thursday, cops said.

The 29-year-old woman was inside the sixth-floor apartment, part of NYCHA’s Eleanor Roosevelt Houses, on Pulaski Street near Stuyvesant Avenue in Bedford-Stuyvesant around 4 a.m. when her 34-year-old ex showed up, according to cops and police sources.

The confrontation between the two turned violent when the ex stabbed the younger man, 26, twice in the left arm, according to police.

The girlfriend called 911 — and the alleged attacker was busted on scene. Charges are pending.

The new flame was taken to the Kings County Hospital Center in stable condition, cops said.
