New footage reveals Chelsea fans rampaging through the streets of Paris before a black man was racially abused on a Metro ahead of a Champions League match.
A court heard how a group of around 150 supporters were filmed by Met Police 'spotters' - some of whom were lighting flares, clambering on cars and goading PSG fans in February this year.
Later, Josh Parsons, 20, Richard Barklie, 50, and William Simpson, 26, prevented a black commuter, Souleymane Sylla, getting onto a busy train .
The three, along with a fourth Chelsea fan, Jordan Munday, were found to have then joined in the chant "we're racist, we're racist and that's the way we like it".
On Wednesday (July 22), the four were handed football banning orders for a combined total of 18 years for their involvement. All four men contested the banning order applications.
District Judge Gareth Branston said they had been part of the "tribal" group which would have left "ordinary members of the Parisian public nervous or frightened".
However, he emphasised that merely being part of the group did not necessarily warrant participation in the disorder.
At one point, the police footage captured Munday deliberately leaving the crowd to confront a man, believed to be a PSG fan.
His arms outstretched, he is heard to say "Where you going you mug?" before he is ordered to return to the group by an officer.
The group were walking towards the Gare De Nord station at around 6.45pm, an hour before the Champions League tie kicked off.
A judge also found that he had joined in the racist singing after Mr Sylla was pushed off the train when it later reached Richelieu Drouot station.
CCTV footage in the moments leading up to the incident also showed Barklie preventing two PSG fans from boarding the train.
Judge Branston told the court Barklie, Simpson and Parsons had all prevented black commuter Mr Sylla getting on the carriage despite the fact there was "clearly room".
The judge found Munday joined in with the racist singing after the incident.
He said Parsons helped push him back while pumping his fist and shouting "Chelsea".
"This was assault," the judge said.
Summing up, Judge Branston said: "The behaviour of the mob on that Paris Metro train, at the forefront of which were Mr Barklie and Mr Parsons, has been seen across this country and beyond.
"It was a racist incident. Mr Sylla says that reference was made to the colour of his skin, though that has not been tested in evidence.
"In any event, the manner in which the group then demonstrated its support for racism is unmistakable.
"The incident has further damaged the already tarnished image of British football in Europe.
"It can only damage the good work done by clubs over the past decades to remedy what has gone on before.
" Chelsea Football Club has written itself to express how appalled it was by what it saw.
"This was abhorrent, nasty, offensive, arrogant and utterly unacceptable behaviour. It cannot be tolerated in a modern, civilised society. It needs to be stamped out.
"Those who succumb to a pack mentality and think they can act in such a hateful way as part of the mob should think again.
"If just one other person is deterred from acting in a like manner in the future by the imposition of these banning orders, then the legislation will have achieved something.
"Certainly, these respondents will be discouraged from behaving in a similar fashion for a long time in the future."
Reacting to today's bans, Mr Sylla told Mirror Online : “I am very pleased with this decision to ban these men.”
In an exclusive interview the 33-year-old said he welcomed the banning orders against four men in connection with the incident. And he said he had been “traumatised” by what happened on the train.
The dad-of-three said: “I welcome what has been delivered by the court today and it is a big step for me, my family and society in general.”
He said he pleased that David Cameron spoke strongly against racism after the incident back in February.
He said: “I want to thank the Prime Minister David Cameron. And if he wants I am quite ready to meet him and continue the fight against racism.
“My six-year-old son has suffered a lot because of what has happened.”
