A woman was followed through a Tube station and sexually assaulted by a man, according to police.
Detectives today released a CCTV image of a man they wish to speak to in connection with the incident at Green Park station on May 12.
Police said a 32-year-old woman had boarded a southbound Piccadilly line train at Russell Square when she noticed a man on the train staring at her.
The man then allegedly proceeded to follow her when she got to Green Park to board the Victoria Line.
The victim moved away from the man as she waited for the train on the platform, but police said he followed her and "touched her inappropriately" as the train pulled in.
A British Transport Police spokesman added: "The woman pushed him away and boarded the train, and the man did not follow.
"Officers have analysed CCTV footage of the incident and have now isolated an image of a man who they think can help with their investigation."
Anyone who recognises the man pictured or has information about the incident, at around 9.50pm on Tuesday, May 12, is asked to call police on 800 40 50 40, or text 61016, quoting reference TSUB/B11 of 23/06/2015. They can also contact Crimestoppers anonymously on 0800 555 111.
