A woman was sexually assaulted after a man appeared to come to her aid when she was struggling to walk on the underground, British Transport Police (BTP) has said.
The passenger in her 40s who has arthritis was approached by a man who assisted her onto the platform at Marble Arch tube station.
He sat with the victim on a bench before making inappropriate comments towards her, the police said.
The offender started touching her inappropriately and trying to kiss her, before a member of rail staff intervened.
The male then left on a westbound service.
CCTV images have been released of a man police wish to speak to in connection with the sexual assault incident at a London Underground station.
Officers are appealing for the public to help trace a male they believe could help with the investigation.
The incident happened on Thursday February 23 at around 3.25pm.
Investigating officer, detective constable Andrew Parkinson, said: “The woman was very frightened during this incident before a member of staff came to her aid.
"We have been making enquiries since the incident occurred and are now releasing CCTV images of a man we would like to speak to as he may have information which could help the investigation."
