Images of three men being sought by police in connection with an incident of alleged racism by Chelsea fans on the Paris Metro on Tuesday evening have been released.

The Metropolitan Police said the men were captured on CCTV ahead of the club's 1-1 draw with Paris St-Germain.

It comes after Chelsea barred two more fans from attending Stamford Bridge, taking the total suspended to five.

Footage taken at the station showed a black man being pushed from a train.

Chelsea manager Jose Mourinho said he was "ashamed" by the incident.

The alleged victim, who has since been identified as 33-year-old Souleymane S, said the fans "should be locked up".

Speaking to BBC Radio 5 live's Drive on Friday he said: "I felt truly wounded to the bottom of my heart that I really couldn't believe it.

"We're in 2015, aren't we, and we're in France. We're in a civilised country and when you are in a civilised country there are certain things you can't do.

'Humiliation'

"For me, it's a humiliation. I was humiliated in my country. I was humiliated in front of my family, humiliated in front of my mother and father."

A group of people can be heard singing "we're racist, we're racist and that's the way we like it" in an amateur video taken at the Paris Metro.

The incident took place at Richelieu-Drouot station in the centre of the French capital and police said the appeal for information is supporting a French police investigation.

Chelsea has said it will ban the five suspended fans from attending Stamford Bridge for life if there is sufficient evidence of their involvement.

A club spokesman said they were writing to Souleymane to "apologise unreservedly" and invite him to attend a game as their guest.

Those with information are urged to call 101 or Crimestoppers anonymously on 0800 555 111.
