A chant of "We're racist and that's the way we like it" from the Chelsea fans was clearly audible on a video of the incident.

Chelsea on Thursday night announced three unnamed supporters had been identified, with the help of other fans, and have been suspended, pending further investigation.

Life bans could be implemented if there is sufficient evidence.

The swift action prevents those supporters from attending Saturday's Barclays Premier League match with Burnley at Stamford Bridge, which has been designated a 'Game for Equality'.

The statement on chelseafc.com read: "Chelsea Football Club is suspending three people from Stamford Bridge as a result of investigations into the incident on the Paris Metro on Tuesday evening.

"If it is deemed there is sufficient evidence of their involvement in the incident, the club will issue banning orders for life.

"We have received substantial information to date following our witness appeal and we are grateful to the many Chelsea supporters who have provided information so far.

"Our investigations are ongoing and we would request any further information is sent to customer.services@chelseafc.com.

"We also continue to cooperate fully with the Metropolitan and Paris police forces who lead the ongoing criminal investigation."

Paris prosecutors confirmed that the alleged victim, identified in media reports as Souleymane, had made a formal complaint.

The French authorities are working with their British counterparts and anyone convicted could face a prison term of up to three years and a fine of up to €45,000.

In an interview with Le Parisien on Thursday, the man named by the newspaper as French-Mauritian Souleymane S called for those involved to be jailed.

He says he could not bear to tell his wife or children about what occurred on Tuesday afternoon at the Richelieu-Drouot Metro station.

The man, reported by Le Parisien to be a chief operating officer at a business close to the Metro station, told the newspaper: "These people, these English supporters, have to be found, punished and should be locked up.

"What happened shouldn't go unpunished."

Reacting quickly to the publication of the video, Chelsea in the early hours of Wednesday morning released a statement describing the incident as "abhorrent" and vowed to take the "strongest possible" action if supporters were found to be involved, leading to Thursday's announcement.

The incident was condemned by British Prime Minister David Cameron, FIFA president Sepp Blatter, UEFA, the Football Association, the Chelsea Supporters' Trust, the Football Supporters' Federation and anti-racism groups Football Against Racism in Europe and Kick It Out.

Chelsea manager Jose Mourinho is expected to join the condemnation at his pre-match media conference on Friday.

Souleymane had no doubt about the reason he was pushed back from entering the train carriage.

"I understood that they were attacking me because of the colour of my skin," he added.
