The footage was released on Monday evening
A group of Russian football fans is being thrown out of France - as GoPro footage appeared to demonstrate that attacks on English supporters in Marseille were well-planned.
The identities of 29 fans were being checked at a hotel near the southern French port city, but authorities told AFP a decision had already been taken to move some of them to a holding centre at the border.
French police are checking to see if any of the Russians are on a list of supporters "considered a risk", said Francois-Xavier Lauch, a top local official in the Alpes-Maritimes area.
The head of a Russian supporters' group said a bus carrying fans on their way to Lille - where there are fears of further violence this week - was stopped near Cannes.
"They want to deport almost 50 people including women who did not take part in anything," Alexander Shprygin, president of the Russian Supporters Union, told Reuters by phone.
"The police are making up for their mistakes three days ago."
"We are in a bus in Cannes and we have been blocked in by riot police. We are not going anywhere for the time being."
He later said the Russian consul had arrived on the scene, preventing what he said was a planned storming of the bus by the police.
Euro 2016 organisers are concerned about the presence of 150 hardcore Russian hooligans who orchestrated violence in Marseille and who the French authorities have described as "hyper violent and hyper rapid."
GoPro footage posted online by Russian fans suggests some of the scenes in Marseille that have overshadowed the start of the tournament were premeditated and well-orchestrated.
A five-minute video shows a group of Russians approaching a main square where English fans were drinking on June 11th, before the two countries faced each other in their Group B opener.
They arm themselves with iron bars, chairs and bottles before attacking England fans, fighting running battles through the streets of the city as their targets flee.
The individual wearing the camera around his waist - who can be clearly identified from press photographs of the violence - is seen appearing to stamp on an England supporter at one point.
The Kremlin has urged Russian fans in France not to react to "provocations" and called on Russian sporting officials to use their influence to ensure supporters behave themselves.
Meanwhile, a Russian MP and executive member of the country's football union has praised Russian hooligans at the European Championships, saying they should "keep it up".
Igor Lebedev posted on Twitter: "I don't see anything wrong with the fans fighting. Quite the opposite, well done lads, keep it up!".
On the pitch, Russia return to action on Wednesday afternoon against Slovakia in Lille.
