Wearing a short pink dress, which rode up during the scrap showing her underwear, the blonde reveller landed multiple blows on her victim during the early hours of Sunday morning.

Three men seem to try and break up the fight before the sister of the woman on the floor steps in and tries kicking the attacker, before pulling her hair.

A male who appears to be a pal of the half-naked woman then steps in and removes her from the situation.

Shortly after, the brawl erupts again - but this time inside the McDonald's.

Having pulled her dress down, the woman makes her way into the fast food chain before launching at the sister of her victim.

The sister grabs her hair once again before kneeing her in the face three times.

A McDonald's security guard is then forced to try and break up the horrific scenes.

It's understood the restaurant called cops in a bid to help defuse the chaos.

A McDonald’s spokesperson said: “An individual involved in an ongoing incident in the local area came into our Leicester Square restaurant.

“Our security team reacted quickly, both contacting the police and de-escalating the situation.

“Anti-social behaviour has no place in our restaurants, and we would like that thank everyone working at the restaurant for responding quickly and professionally.”

The Met Police said no arrests were made.

A spokesperson said: "Police were called in the early hours of Sunday, 10 September to reports of a group of people fighting in Leicester Square.

"There were no arrests. Enquiries are ongoing."
