JUST IN: Brooklyn man who disarmed and shot subway train aggressor will NOT be charged: Brooklyn DA

Oren Yaniv, a spokesperson for the Brooklyn District Attorney's Office, said in a statement Friday: "Yesterday's shooting inside a crowded subway car was shocking and deeply upsetting."

"The investigation into this tragic incident is ongoing but, at this stage, evidence of self-defense precludes us from filing any criminal charges against the shooter," explained Yaniv, according to ABC News.

The incident occurred around 4:45 pm on a northbound A train in Brooklyn at the Hoyt-Schermerhorn station and went viral on X after video of the shooting was published on the platform.

The 32-year-old passenger was approached by an "aggressive" 36-year-old male who started a verbal and physical altercation with him, police said.

The 36-year-old male can be seen in the video throwing multiple punches. He then pulled out a knife or razor blade and threatened the passenger. The man put the knife down and pulled out a firearm. He menacingly approached the passenger and pointed the firearm at him, according to police.

The 32-year-old passenger disarmed the man and shot him in the head with his own gun, police said.

The man who was shot was transported to the NewYork-Presbyterian Brooklyn Methodist Hospital in critical condition. His condition remains the same at the time of this writing.

This comes as New York City heightened its police presence at subway stations and on trains in an attempt to deter crime, which has drastically increased in the transportation system in recent years. New York Gov. Kathy Hochul deployed the National Guards to subway stations across the Big Apple to conduct bag checks and establish an authoritative presence.
