Update — Nov. 19, 7:46 a.m. EST:
A 34-year-old man was taken into custody Tuesday in connection with the fatal push of a man in front of a New York subway train over the weekend.
Bronx resident Kevin Darden was taken into custody after another man said he had been pushed by Darden in a subway station, the New York Times reported. Darden has been charged with murder, police said.
The man said Darden pushed him to the platform of the West Fourth Street station on Nov. 6, the New York Times reported. The man told police he believed his attacker was the same man in surveillance footage released on Monday.
Another person said Darden had robbed him at another subway station 30 minutes before the fatal push, the New York Daily News reported.
New York police are seeking a "person of interest" who may have pushed a 61-year-old man in front of a subway train.
Wai Kuen Kwok died Sunday morning after he was struck by a subway train at the 167th Street and Grand Concourse station in the Bronx. He was pushed by an unknown man, who then fled the scene, the New York Police Department said.
Kwok, a father of two, had been waiting for the train with his wife on their weekly trip to Chinatown for dim sum and shopping, the New York Times reported. His wife saw a hand push her husband, the Times reported, but she was not able to clearly see the fleeing man's face. No words were spoken, and no motive is known.
Police on Monday told CBS News they believe they are close to finding the man.
Based on surveillance video, the New York Post reported one person had identified the man as a 35-year-old panhandler. Authorities have not officially identified him or made an arrest.
In 2012, two people died in separate incidents when they were pushed in front of trains. No other fatal pushes have been reported since.
