Teen slaps Asian woman on D line

An Asian woman was slapped on a Brooklyn subway train by a teenage stranger who told her, “Get off my train, you don’t belong here,” cops said Wednesday.

The 50-year-old victim was riding a Coney Island-bound D train through Borough Park when the hateful teen confronted her, smacking her in the back of the head.

The victim got off the train at the Ninth Ave. stop.

The attack is the latest to come to light as the NYPD battles a surge in hate crimes against Asian New Yorkers.

Cops released a surveillance photo (inset) of the suspect and asked the public’s help identifying her and tracking her down.

The suspect is described as Black, about 18, 5-feet-5 and 150 pounds. She has long braided hair and was wearing a green sweater and a face mask.
