A racist white man in Chicago allegedly hurled racial abuse at the wrong black man on a Chicago train, the Chicago Sun-Times reports.

In a video shot on the platform of the Clark/Lake station on the city's Blue Line CTA commuter train, the white man is seen hurling abuse at the other passenger.

After eyewitnesses said the white man in a pink tank top used the N-word.

The black man begins to take his button-down shirt off.

"My God! Y'all playing, man," he says by way of warning.

He then removed his glasses and pursues the white man, who he punches, knocking him to the ground with his head over the edge of the platform above the tracks.

The first man then appears to walk away but someone comes up to the white man, punching him and knocking him down into the train tracks.

“Call another motherf*cker a n*gga,” someone yells. “What the f*ck is wrong with you?”

The white man is then helped to safety.

No one has filed a report about the incident and neither man has been identified.
