An elderly woman was repeatedly kicked in the face and body during a savage Bronx subway attack caught on video. The video shows the man assaulting the 78-year-old victim as she is sitting in a northbound No. 2 train around 3 a.m. March 10, police said. The woman, who was alone, tries to defend herself as he continues to attack her — all while other straphangers can be heard shouting in the background. As the train was stopped at Nereid Avenue, the man yells something at his victim before turning around, looking at the camera and shouting, “WorldStar that” — referring to the popular social media page that is filled with violent videos. He then got off the train.
