The NYPD is currently searching for a man they believe to be responsible for pushing another man onto a subway track where he was fatally hit by an oncoming train.

According to police, Ki-Suck Han, 58, of Queens, N.Y., was thrown onto the tracks Monday afternoon just after 12:30 from a crowded train platform at the 49th Street and Seventh Avenue station in midtown Manhattan.

Multiple news outlets are reporting that eye witnesses told authorities Han tried to climb back on to the subway platform, but was hit by an oncoming train before he could scramble to safety as other bystanders watched in horror.

"I just heard people yelling. The train came to an abrupt stop about three-quarters into the station and that's when I heard a man was hit by a train," Patrick Gomez told ABC News affiliate WABC.

A surveillance video released by police and obtained by ABC News reveals that an argument took place with the victim and suspect moments before Han was pushed onto the tracks. The suspect is heard telling the victim to stand in line "and wait for the R train," according to the news network.

Other witnesses reportedly told police the suspect was mumbling to himself shortly before the altercation took place on the crowded platform. Authorities told reporters that they are exploring the possibility that the suspect could be mentally disturbed.

In the moments after Han was hit by the Q train, the suspect fled from the scene. Police then set up a command post outside the train station Monday night searching nearby surveillance cameras to try and get a clear image of the suspect.

Police have released a description of the NYC subway pusher, describing him as a black male, 5-feet-10 to 6-feet tall and weighing about 200 pounds. He has dreadlocks and was last seen wearing a gray t-shirt, a dark jacket and a cap.
