Police said the 61-year-old man was standing on the platform for the A/C trains inside the Fulton Street subway station in Lower Manhattan just before 11:30 a.m. when he was pushed onto the tracks as a train was coming into the station.
It's not clear if he was struck by a train, but police said he did not make contact with the electrified third rail.
He was taken to NewYork-Presbyterian Hospital where he was treated for minor injuries.
The suspect fled the station and police are searching for him.
A/C/D/F trains in the area were heavily impacted.
The incident comes just over a week after 40-year-old Michelle Go died after she was pushed onto the subway tracks at a Times Square station.
The suspect in that case was arrested.
