Police are searching for a man in connection with an alleged rape at Embankment in central London.
The victim, a woman in her late teens, is said to have been assaulted in Victoria Embankment Gardens on Villiers Street in the early hours of August 16 of last year.
A member of the public came across the victim after she had been raped, and helped her before police were contacted.
A 30-year-old man was arrested on suspicion of rape on the same day, police said.
The man was questioned and then released under investigation.
Officers from the Met's Central West safeguarding team have released an image of a man they believe could assist the ongoing investigation.
If you recognise the man in the picture and you have information, call police on 07584 593 393 quoting CAD1003/16AUG19, or 101.
