British police have spoken to three men in connection with the alleged racist incident involving Chelsea supporters on a Paris Metro train.
Scotland Yard had released images of the men they believed were among a group of supporters who allegedly refused to let a black man board the train while chanting a racist song on the way to Chelsea's Champions League draw against Paris St Germain on Tuesday.
A Metropolitan Police spokesman said on Sunday that the three men had now been identified and the force was liaising with the French authorities.
None of the men sought by Scotland Yard have been arrested.
A police spokesman said the force cannot arrest people for offences which happen outside the UK but "a number of people" have now been spoken to in relation to the incident.
Footage posted online showed the commuter, named in reports as Souleymane S, being pushed back on to the platform amid chants of "we're racist, we're racist and that's the way we like it".
Five people have so far been suspended from Chelsea's Stamford Bridge ground following investigations into the incident.
The Premier League club have reiterated their promise to ban for life anyone proved to have been involved in the altercation, and are helping police in the UK and Paris.
Chelsea manager Jose Mourinho said the club were "appalled" by the racial abuse, adding that owner Roman Abramovich was "disgusted".
