Police are seeking a gang of men, believed to be Chelsea fans, who were heard shouting racist chants at a London train station.

The incident, which took place at London St Pancras on Wednesday evening, happened the day after fans of the same football club allegedly pushed a black man off a Paris Metro train while shouting a racist chant.

An investigation is currently under way after a member of the public reported the men, who had travelled by train from Paris Gard du Nord.

It is believed they were returning home after attending the Champions League 1-1 draw against Paris St Germain on Tuesday.

Five people have so far been suspended from the club's Stamford Bridge ground following investigations into the incident on the Paris Metro train.

Chelsea have reiterated a promise to ban for life anyone proved to have been involved in the altercation.

The man pushed off the train, identified only as 33-year-old Souleymane, has said the incident is the club's "responsibility".

Chelsea have said they are "appalled" and apologised and invited Souleymane and his family to London.
