A man who inappropriately touched a woman on a busy train to Dartford through Welling is being hunted by police.
British Transport Police investigators have released an image of a man they want to speak to about the incident which took place at around 5pm on February 28.
Investigating officer Detective Constable Andy Parkinson, said: “The 35-year-old victim was travelling on the busy 4.39pm Victoria to Dartford service.
“During the journey a man stood behind the woman and inappropriately touched her.
