Two men slashed each other as an early-morning clash turned violent on the subway platform at Grand Central on Tuesday, police said.
The men, ages 30 and 50, got into a fight on the northbound 4, 5 and 6 train platform at 42nd Street-Grand Central minutes before 1 a.m., authorities said.
They knifed each other on the arm, with one treated on scene by emergency responders and the other taken to Bellevue Hospital, where he was described as conscious and alert, police said.
The nature of the dispute was not immediately clear.
Also unclear is whether the two men knew each other.
Both men were taken into custody but not immediately charged, sources said.
The older man has several prior arrests, including busts for robbery and rape, according to the sources.
The younger man has no criminal history, the sources said.
