The son of Big Fat Gypsy Weddings star Paddy Doherty appears to have been filmed brawling at a traveller site and trying to "bite off" a rival's ear.
John Doherty - son of the Celebrity Big Brother winner - allegedly bit a member of the Joyce clan after the man knocked him to the ground in front of a baying crowd.
Women and children could be heard screaming in terror as the pair traded blows at the site, believed to be in Manchester.
Bare-knuckle boxer Paddy Doherty, 58, was said to be among the crowd which had to intervene and separate the fighters after his son "bit" the man and chased him into a trailer.
The chaotic scenes - captured on a mobile phone - were uploaded to social media and have been viewed more than 150,000 times.
