One man died and two others were hurt after a fight at a train station in Harlem on Saturday.
Police say one man pushed another man, unprovoked, onto the train tracks at the 110th Street Station. They say a witness then jumped onto the tracks to help.
Officers say the suspect followed and started fighting with the good Samaritan near the tracks. They say the suspect then made contact with the third rail of the subway.
Authorities say the suspect was pronounced dead at the scene.
