NEW YORK — The daughter of a man pushed in front of a subway train and photographed a split-second before his death said Wednesday after a suspect was arrested that it “would have been great” if someone had helped her father up but “what’s done is done.”

A freelance photographer for the New York Post was waiting for a train Monday afternoon when he said he saw a man approach 58-year-old Ki-Suck Han at the Times Square station, get into an altercation with him and push him into the train’s path.

The Post photo in Tuesday’s edition showed Ki-Suck Han with his head turned toward the train, his arms reaching up but unable to climb off the tracks in time.

The photographer, R. Umar Abbasi, told NBC’s “Today” show Wednesday that he was trying to alert the motorman to what was going on by flashing his camera.

He said he was shocked that people nearer to the victim didn’t try to help in the 22 seconds before the train struck.

Police charged a homeless man, Naeem Davis, on Wednesday with murder.
