Footage of two New York City police officers opening fire at a subway station as they confronted a man holding a knife shows they fired at him as he was standing still, his arms by his side and his back to a train.

Police say that a man suspected of not paying the subway fare did not follow instructions and threatened officers with a knife.

Dramatic police body camera footage shows cops repeatedly warning a deranged suspect to drop his knife — then firing a taser to subdue him — before a “friendly fire” shooting left cop and two bystanders injured at a Brooklyn subway station.

A man who police shot on a crowded Brooklyn subway platform Sunday — after, the NYPD says, he skipped a fare and threatened officers with a knife — remains in a hospital bed and unable to walk, his attorney said Friday.

The NYPD has released body camera video of a police shooting at a subway station in Brooklyn on Sunday, that left both a suspect and a bystander in critical condition, and injured an officer and one other bystander.

A subway fare-beater accused of threatening a pair of NYPD officers with a knife, sparking a showdown that resulted in four being injured by police gunfire at a Brooklyn L station, was indicted Friday for assaulting the officer struck by his partner in the friendly fire shooting.
