Witnesses are being sought to a fight on a South Yorkshire train which broke out in the wake of Doncaster’s St Leger race meeting.
During the confrontation a passenger on the 21.49 service from Sheffield to Cleethorpes was headbutted by a man.
Two women and then another man also became involved.
The incident took place in the first class carriage as the train travelled between Doncaster and Scunthorpe on September 14.
The group involved were smartly dressed and may have been returning from the race festival.
British Transport Police have released CCTV images of five people they are trying to trace, three men and two women, who they believe may be able to help with their inquiries into the crime.
PC Richard Soare said: “The train guard reported a fight breaking out on the service and a passenger being headbutted by a man. Two women and an another man then also became involved.
“We believe that a fourth man also got drawn into the fight and was assaulted – he left the train at Allthorpe.”
The group all left the train at Scunthorpe. One of the women was wearing a white dress which was covered in blood after the incident.
PC Soare said: “After viewing CCTV of this incident we are now releasing images in an attempt to trace five people we believe may have vital information about this incident. We would also like to appeal for the man who was assaulted to get in touch with us as well.
“If anyone was travelling on the service and witnessed the incident I would urge them to contact us.”
