A New York City Police officer shot and killed a man allegedly armed with a knife in Brooklyn on Tuesday afternoon. It happened just before 3 p.m. inside a NYCHA apartment building on Christopher Avenue between Glenmore and Pitkin avenues in Brownsville.

One officer deployed a Taser, but it failed to subdue him, police said. A second officer then fired two shots, striking the man in the chest, authorities said.

Police responded to 108 Christopher Ave. in Brownsville after a woman called 911, reporting that her ex, and father of her children, was threatening her, and she believed that he was on the way to kill her.
