The woman received 16 stitches.

The woman sustained head lacerations.

The NYPD is seeking the alleged pusher and three of his friends in connection with the assault.

The man sued the city after he dared to dance behind some unsuspecting cops outside Grand Central and was shoved to the ground.

The police are seeking a "person of interest."

A witness said: "One girl upstairs decides to come out of bathroom. She refused to give him money, and he pushed her in front of the train."
