It shows the woman running from the elevated platform in the Queens section of New York City Thursday night.

Witnesses tell police she had been following the man closely and mumbling to herself. She got up from a nearby bench and shoved him as the train pulled into the platform.

It's the second time this month someone has been shoved to their death on subway tracks.

Ki-Suck Han was pushed in front of a train in Times Square on Dec. 3. A photograph of him moments before the train hit him was published on the cover of the New York Post, causing an uproar.
