GRAVESEND, Brooklyn (WABC) -- Police have released video of a violent attack and robbery in a Brooklyn subway station. The female suspect grabbed the 60-year-old female victim from behind while she was using a MetroCard machine at the 86th Street N station on Sunday. The video shows the suspect throwing the victim to the ground, punching and kicking the woman repeatedly, and dragging her across the floor as he tries to steal her purse. Moments later the suspect is seen on another security camera breathing heavily, wearing the same mask, and holding her rolled up blue hoodie in her hand.
