A member of a right-wing group has been jailed after mistakenly attacking a man during a mass brawl who turned out to be on the same side.
Dale Lutton, 27, punched another member of right-wing group Generation Identity, thinking he was from leftist organisation Anti-Fa, during the fight in a car park in Sevenoaks, Kent.
Maidstone Crown Court heard the pair eventually realised their mistake and shook hands.
However, Lutton, from Portadown in Northern Ireland, was jailed for 16 months after he was filmed joining in with the fighting as soon as it began, throwing multiple punches, albeit at someone from his own group.
He was one of four people involved in the fighting on April 14, 2018 who were handed a jail sentence last Friday.
Deidre McTucker, 43, from Dublin in Ireland, was jailed for 12 months after being found guilty of violent disorder at a trial in September.
She was filmed grabbing a woman by the hair before punching her repeatedly in the face during the brawl in a Marks & Spencer car park.
Paul Carbine, 33, from Wickford, Essex, was also jailed for 12 months, while Sebastian Seccombe. 20, from Consett, Durham, was sentenced to two months in a young offender institution - both for violent disorder.
The four had attended a conference held by Generation Identity which had to be moved from a pub after a protest from Anti-Fa.
The court heard how the rival gangs acted like “football hooligans” during the car park clashes.
Prosecutor Patrick Dennis said: "This was a wholly unsavoury, unnecessary and unlawful incident. They were acting like football hooligans.
"One side was a right-wing group called Generation Identity. On the other was a left-wing group called Anti-Fa.
Mr Dennis added: "Footage shows members of both groups engaging in hand-to-hand combat.
"There can be no doubt that ordinary members of the public were frightened by what they witnessed."
Detective Sergeant Dan Barker of Kent Police said: "The actions of these four people and others involved in fighting that day were completely unacceptable.
"Members of the public should be able to go about their daily business without having to witness such mindless acts of violence, as has been demonstrated by the sentences imposed by the judge in this case.
"All four now have plenty of time behind bars to consider whether the juvenile behaviour they displayed was really worth it."
