Footage shows a man, alleged to be Jamar Newton, 41, of Brooklyn, wearing a T-shirt that read "I am black history" while carrying out the attack at the Union Square subway station on Saturday around 9:08 p.m.
"Don't look at me, or I'm going to hit you," the suspect allegedly yelled to another man who glanced in his direction on the platform. "If you come any closer, I'm going to hit you!"
New York City Police Department officials said the suspect attacked the 44-year-old victim after they had a dispute.
Footage shows the suspect removing a hammer from his blue backpack and swinging it down on the victim's head, causing the man to fall on the tracks.
The man was pulled to safety by good Samaritans and taken to a local hospital, where he received seven stitches for the cut on the back of his head.
The man is in stable condition, police said.
