A subway rider in New York made a citizen’s arrest of a violent straphanger who repeatedly kicked a passenger on a Brooklyn train and hurled a racial slur at the woman.

Anna Lushchinskaya, 40, was charged with felony assault following the wild Tuesday morning incident around 8 a.m. aboard the train in Sunset Park, the NYPD said.

In two videos posted to Twitter by another rider — who appeared to detain Lushchinskaya on the 36th Street station platform until the cops showed up — the suspect can be seen unleashing the attack.

“F—k off! F—k off! F--k off!” Lushchinskaya shouts to a silent woman who is standing next to her and appears to be preoccupied with her phone, one of the clips posted by Twitter user @PlatanoMan shows.

Lushchinskaya appears to hit the woman’s hand.

The maniacal, blonde-haired woman is then seen taking off her sunglasses, putting her hair up in a ponytail, and pulling an umbrella out of her bag.
