Met detectives have released a picture of a man they want to identify in a 1970s sexual assault case.
The offence, reported to police earlier this year, is alleged to have taken place at student accommodation at a hospital in Ealing in late 1977 or early 1978, when the victim was aged 19.
So far, officers have been unable to fully identify the man in the photograph, although his first name is thought to be Gary.
Police released an image of a man they want to identify dating from the late 1970s and asked anyone who recognises him to get in touch.
“Despite extensive inquiries being undertaken, the man, who officers believe may be called Gary, remains unidentified,” the force said in a statement.
“The image released is from the late 1970s, but we are hoping that someone who recognises the man can tell us who and where he is.
“If the man in the image is you, please contact police immediately."
