New York City police have taken a woman into custody who they believe is responsible for the death of a man who was pushed in front of an oncoming subway train.

Police on Saturday said the 31-year-old woman "made statements implicating herself."

She has not yet been formally charged.

Sunando Sen, a 46-year-old Queens resident who was born in India and ran a printing shop, died Thursday night when a woman who had been muttering to herself on a train platform in Queens suddenly knocked him on the tracks as a train entered the station.
