Subway Push: Suspect Charged Over NYC Murder

New York City police have arrested a homeless man over the death of a man who was pushed onto subway tracks and photographed just before a train struck him.

Naeem Davis, 30, was taken into custody on Tuesday after a security video showed a man fitting his description working with street vendors near the Rockefeller Center.

Police said Davis made statements implicating himself in the death of father-of-one Ki Suk Han.

Davis was arrested on a second-degree murder charge on Wednesday.

Witnesses told investigators they saw a man talking to himself on Monday afternoon before he approached 58-year-old Mr Han, from Queens, at Times Square station.

Onlookers said the man got into an altercation with Mr Han and pushed him into the train's path.

His death gained worldwide attention after the New York Post published a photo on its front page of Mr Han with his head turned toward the train and his arms reaching up, but unable to climb off the tracks in time.

The picture, shot by freelance photographer R Umar Abbasi, prompted questions about why nobody, including the photographer, seemingly tried to help the man.

Mr Abbasi told NBC's Today show that he was trying to alert the driver as 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.

"It took me a second to figure out what was happening ...I saw the lights in the distance. My mind was to alert the train," Mr Abbasi said.

"The people who were standing close to him ...they could have moved and grabbed him and pulled him up. No one made an effort," he added.

Subway trains generally arrive at stations at a speed of 25mph (40kph), but it is not clear how fast the train was going when it struck Mr Han.

The waiting area is a narrower than at other underground stations, but the platform is still about a dozen feet (approximately 4m) wide.
