Police were called after a huge crowd flouted lockdown rules to watch an "organised" fight near a pub in Walker, Newcastle.
Dozens of spectators were filmed screaming and shouting as two men, wearing boxing gloves, brawl in broad daylight.
The fight was even streamed on Facebook Live, with footage showing a boxer knock his foe down to the ground.
Scores of youngsters, clutching their phones, then rush towards the winner to celebrate with some hugging him.
Northumbria Police received multiple calls about the fight, which has been slammed by locals who branded them "idiots" for ignoring social distancing rules.
"I can't see my family or friends, yet some people think they are invincible battering each other in car parks," fumed one nearby resident.
Footage shows onlookers moving around outside the Crockets Hotel, with around a dozen vehicles parked up outside.
Among them, scrap vans and even a lorry - which was acting as a makeshift stand for spectators to get a view of the action.
"We received reports that an organised fight had been arranged at a premises on Mitchell Street, Newcastle, on Friday, May 15," said a Northumbria Police spokesperson.
“Officers attended and on arrival, a number of those present dispersed without issue and neighbourhood policing teams remained in the area to carry out patrols.”
However, footage of a widely-shared livestream of the fight is still on Facebook.
Over 4,500 people have watched the clip to date.
