A blind woman was sexually assaulted by a man who pretended to offer her help at a busy central London Tube station, police said.
Detectives today released a CCTV image of a man they want to speak to in connection with the incident.
The woman had been travelling on a southbound Northern Line train with her guide dog and suitcase at around 10am on December 3 last year.
Police said she became aware of a man next to her as she got off the Tube at Waterloo.
Posing as a Good Samaritan, he offered to help the woman and took hold of her.
He then sexually assaulted her before fleeing the scene, police said.
Another passenger came to help the woman and took her to the ticket hall, where she reported the incident to staff.
British Transport Police have released CCTV images of a man they wish to speak to in connection with the incident.
Detective Constable Suleman Yazdani said: “The man who committed this offence masqueraded as a Good Samaritan, purely so he could take the opportunity to sexually assault his victim.
“We work extremely hard to make sure the Tube is a place where women can travel without the fear of unwanted sexual behaviour and are determined to find the person responsible for this assault.
“Who is the man in the picture? I think he has information which can help us.”
