NEW YORK - Police in New York City on Friday were hunting for a woman in her 20s suspected of pushing a man to his death under an oncoming subway train, the second such incident in less than a month. The incident happened Thursday evening at about 8:00 pm (0100 GMT Friday) at a station on the number 7 line in the Queens borough, police said. The suspect  pushed the man as the train was pulling into the station. He apparently had his back to the woman and did not see her.
