NEW YORK -- A man was killed Monday after being pushed by another man onto the subway tracks in a New York city subway station, police said.

According to WPIX, the incident happened at the N, Q, R station at West 49th St. and Seventh Avenue at roughly 12:30 p.m. on Monday.

Investigators say the two men were seen arguing on the platform. Moments later, 58-year-old Ki-Suck Han was shoved onto the tracks by the suspect and struck by a southbound Q train.

Han desperately tried to scramble back to the platform as onlookers screamed, shouted and frantically waved their hands to try to get the train to stop. According to the New York Post, a freelance photographer flashed his camera repeatedly to try to get the train conductor's attention, and captured Han's desperation efforts in the process.

Efforts made by a nurse in the area to revive Han after he was hit by the train were unsuccessful. He was transferred to a hospital, where he was pronounced dead.

Witnesses say Han was trying to reason with the man who pushed him. They say that man was acting deranged and Han was trying to get him to calm down.

Police had a suspect in custody for questioning Tuesday.

According to the Post, Han had left the house angrily that night after an altercation with his wife, who said Han may have been intoxicated.

Police describe the suspect as a black male with dreadlocks, last seen wearing a dark jacket, a gray t-shirt and a cap. No arrests have been made as of Tuesday morning.
