A video of a racially charged fight on a Brooklyn D train that landed a woman behind bars has gone viral.

The video shows a woman cursing, kicking and spitting on a fellow commuter before smacking her with an umbrella and keys.

Police identified the assailant as 40-year-old Anna Lushchinskaya, of Gravesend. The footage was taken Tuesday morning by a straphanger who goes by Juan "Platano Man" Ayala.

Police say the ordeal began when two women bumped into each on the crowded train. News 12 is told that a man who tried to intervene suffered minor scratches.

The man who recorded the video says he had to detain the suspect until police arrived on scene.

Police say Lushchinskaya was arrested at 36th Street. She's charged with felony assault.
