A man threatened passengers and performed martial arts moves on a train between Leeds and Sheffield.
The incident took place at around 1.30pm on Satruday, December 13 on an Arriva Cross Country service.
The man was acting strangely and performing martial arts moves on Sheffield station before he boarded the train to Leeds. Once on the service he began to verbally threaten a number of passengers with violence.
The train was met at Leeds by British Transport Police officers, and a 27-year-old man from Sheffield was arrested in connection with the incident. He has since been released on police bail.
PC Gary Reader, investigating for BTP said: “This was completely unacceptable behaviour which left a number of passengers fearing for their safety
“We would like to hear from anyone who may have been travelling on the service and witnessed the man’s actions. I would particularly like to trace a couple who we believe may have also been threatened but left the service at Leeds before officers could get their details. Anyone with information is asked to contact British Transport Police on 0800 40 50 40 or via text on 61016, quoting background reference PSUB/B6 of 19/12/2014.
