New York City police say a man has been shoved in front of a subway train and has been killed.

Investigators are searching for the woman believed to have pushed him Thursday night in Queens.

It's the second time a man was shoved to his death on subway tracks this month. 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 and caused an uproar.

Thursday's subway killing happened on a platform for the 7 train, which connects Manhattan and Queens. Witnesses tell police a heavyset Hispanic woman in her 20s had been following the man and mumbling. They say she was wearing a blue, white and gray ski jacket and sneakers.
