Grand Central Station fist fight leaves man knocked out

This is the shocking moment two men began fist fighting in the middle of Grand Central Station in New York.

Horrified bystanders began filming when the two young men started squaring up to each other following an off camera dispute.

One man, more muscular with long hair appears to be goading his rival threatening him with: ‘Let’s fight then,’ while the second man goes chest to chest with him menacingly.

However, after the second man squares up too close, his larger rival throws a wicked haymaker to his face, knocking opponent unconscious briefly.

Uncomfortable footage captures the taller, skinnier man lie sprawled face down on the floor seemingly out for the count.

However, in a second clip filmed a short while later, the man is back on his feet trying to continue the fight as onlookers try to separate them.

The broader man who had already landed what seemed to be a finishing blow is seen trying to make his exit stalked by his rival now seeking revenge.

One clip shows the two men now grapping on the floor with the muscular man on top of his chest throwing punches downwards

A final third clip then shows the two men now grappling on the floor with the muscular man on top of his chest throwing punches downwards.

The skinnier man is seen trying desperately to hurt his long-haired rival by pulling at his locks while they continue to scuffle.

Eventually NYPD officers show up to separate the pair at which point the recording ends.
