Police say the suspect pushed off-duty worker Sabrina Scott onto the tracks at the East Broadway station in Chinatown on February 4.
A Good Samaritan heard the victim's cries and rescued her, carrying her off the tracks to safety.
The attacker ran away.
The suspect is described as a Hispanic man, 35 to 40 years old, 6' tall, weighing 200 pounds, with a pockmarked face.
