Police are looking for this man after a teenager was repeatedly groped on a crowded train.
The 17-year-old had to stand in the vestibule area after getting on the 5.09pm Leeds to Liverpool Lime Street service on Thursday, June 19.
PC Kevin Webster, from British Transport Police, said: “A man, who also boarded the service at Leeds, stood close behind her.
“A short while into the journey the man moved to the side of the victim then began to inappropriately touch her.
“The man continued to indecently assault the victim throughout the journey until the train arrived in Dewsbury where he left the service.
“This was an incredibly frightening experience for the girl, who has been left extremely shocked and distressed.”
“British Transport Police takes sexual offences on the rail network very seriously and will always fully investigate all incidents reported to us.”
Anyone with information is asked to contact British Transport Police on 0800 405040, or text 61016, quoting reference PSUB/B6 of July 11.
