Police have issued a CCTV still of a man they want to trace after a woman reported a man performing an indecent act on a train to Sheffield.
He was reported to British Transport Police by a fellow passenger, who was travelling on the service from Manchester Airport.
Constable Matthew Peters, who is investigating the incident, said: “The victim, a 49-year-old woman from Burton upon Trent in Staffordshire, was travelling with three of her friends in the first-class carriage on the service.
“When she turned around a man was performing an indecent act in front of her.
“The group alerted the train guard who removed the man from first class and contacted police.
“Officers met the train at Sheffield but the man had already left. “After viewing CCTV footage, we have obtained an image of a man we believe may have information about the incident.”
Anyone with information about the incident on Saturday, June 22, is asked to call British Transport Police on 0800 405040.
