A "appalling" mass brawl erupted on Freedom Day which saw five people hospitalised and six arrested as a street in Luton was left with pools of blood.
Shocking footage shows a large crowd battering one another with what police believe were bats, knives and machetes in the early hours of Tuesday.
The chaos broke out at about 12:45am, just as Brits across England celebrated the end of almost the 18-month lockdown rules.
The video, posted on social media, shows the group going at each other near Dunstable Road in the Bury Park area.
Bedford police said they were called to the scene at about 12:45am and that one of those hospitalised is believed to have suffered life-changing injuries, while the others are not believed to be either life-threatening or life-changing.
Five people have been taken to hospital after a mass brawl erupted in Luton on Freedom Day
One person had to be given first care at the scene, police said.
The horrifying footage shows one man being targeted with different objects before he is dragged to the floor and hit.
Another individual appearing to lie helplessly in the middle of the street is then punched by another man before the street clears.
The video cuts then to another man being circled by a group as he is brutally beaten.
One man in his 20s was arrested on suspicion of attempted murder and another five in their 20s to 40s were arrested on suspicion of violent disorder following the fight.
The brawl took place on the very same day that lockdown effectively came to an end in England
As of Tuesday, two men remained in hospital as they were treated for their injuries, while road closures in the Dunstable Road and Kenilworth Road areas were put into place to assist with the investigation.

Cllr Simmons MBE, Leader of Luton Council said: “I am utterly appalled and saddened to hear of the dreadful outbreak of violence in our town last night. Such behaviour is completely unacceptable at any time, but it is especially distasteful that it has taken place at the time of an important celebration for so many throughout Luton.
“An incident such as this not only serves to give our town and its population a bad name, but increases our resolve to clamp down on all violent crime.
"Our residents do not deserve to experience this and we will do all we can to ensure people’s peaceful lives are not threatened in any way."
