A mass brawl breaks out on Alabama harbor as a dispute over boat parking leads to men, women and folding chairs fighting

Shocking video footage shows the moment a mass brawl broke out between a group of white and black people on an Alabama riverbank, in which a woman was hit on the head with a chair.

A witness claimed the fight started with an argument over a pontoon boat blocking the wharf where a riverboat was trying to dock.

Video shared on social media shows horrific scenes of violence spilling over, with sides seemingly split on racial lines — though it’s not yet clear if the melee was racially aggravated.

Men are seen gouging eyes and hurling punches at each other’s heads, as a woman lies beaten on the floor while a man smashes a chair over her head in a vicious attack.

A man is even seen swimming from across the river to the other side of the river to join the fight.

Footage seems to show the fight starting in a fight between a white man and a black man at the end of the boardwalk.

In a flamboyant gesture, the black man tosses his cap to a watching crowd above, seemingly anticipating a brawl.
