Police are appealing for witnesses following a fight on a train at Leeds station.
The incident happened at around 7pm on Saturday May 3 on the 5.50pm TransPennine Express service from Scarborough to Leeds.
During the journey, a 38-year-old woman from Barnsley, who was travelling with her partner and child, became involved in a dispute with a group of four women and three men.
As the train pulled into Leeds station, a scuffle broke out and the woman subsequently made an allegation of assault.
PC Craig Virco of British Transport Police Leeds, said: “We have examined CCTV of the incident and are following several lines of enquiry, but I would like to hear from passengers on the service as they could have key information about what took place.”
The group are described as ranging in age from 20 to 65 years old and were accompanied by three children.
PC Virco said: “Violence on the rail network is unacceptable and we treat all reports seriously. This was a crowded train and I would ask anyone who witnessed the incident to get in touch with us.”
Anyone with information is asked to contact British Transport Police on 0800 405040, or text 61016, quoting reference PSUB/B7 of 05/06/2014.
