A hunt has been launched for a man who masturbated through a hole in the pocket of his trousers in front of a woman on the Elizabeth Line.
He did the act on the train from Tottenham Court Road to Stratford shortly after 9.15pm on February 4.
Afterwards, he sat down opposite the woman and exposed himself before leaving the train at Stratford.
The British Transport Police have launched an investigation and, on Tuesday, released an image of a man they believe could help.
