 It shows a crowd of men throwing punches in the road as opposing fans clashed.

One man appears to have lost his footing as he lies prone on a zebra crossing.

As he comes to his hands and knees to get up, a brute launches a vicious punt at his skull.

It finds its mark and the defenseless man is knocked out cold, with his head bouncing off the tarmac with a sickening crack as he crumples.

Two fellow fans try and lift him to drag him out of harm's way, but his body hangs lifelessly as his head droops limply forward.

The fight continues as the men can be heard shouting at each other, thought it is not clear what they are saying.

The user who posted the video claims to be the account of Gruppa OF and refers to the organisation as the "#1 hooligan group in the world".

They caption the post with the date and the phrase: "Leicester win. 1 West Ham KO."

The footage prompted outrage in the comments.

One social media user wrote: "Attempted murder that - jail time."

Another fumed: "Booting a man in the head and then running away. Cowardly."

Despite their win, Leicester were relegated to the Championship yesterday as Everton stayed up on a dramatic final day of Premier League action.

Manager Dean Smith is reportedly set for talks with the club's board over his future after only being appointed as caretaker coach in April.

Leicestershire Police and East Midlands Ambulance Service have been contacted for comment.
