The British Transport Police are investigating four possible Chelsea fans for alleged racist and abusive behaviour on a train from Euston to Manchester on the day of the Capital One League Cup Final.
BTP says officers were called to Stoke-on-Trent station to remove the four men after numerous complaints on Sunday.
Police say another four passengers left the train on their own accord as well.
Witnesses say the four men were being nasty and offensive against minority community passengers.
One source says a girl was crying and a black man left the carriage after racist comments were made.
A Chelsea club representative says they are aware of the allegations.
If it is confirmed Chelsea fans were involved they will assist the BTP with the investigation.
A BTP spokesperson said:
Rail passengers and staff have the right to travel and work in peace. Abusive behaviour on trains and at stations is unacceptable and we will not hesitate to investigate any such incidents.
