Police are hunting a man after a woman was ambushed and sexually assaulted in a Wembley alleyway.
The woman, in her 20s, was attacked as she walked up the alley between Manor Farm and Athlon Road at 6.25pm on August 3.
Two passersby helped the victim after the asssault and police are appealing for them to come forward.
Detective Constable Annabella Davies, who is leading the investigation, said the two witnesses had left the scene before officers arrived.
DC Davies said: “This was an appalling attack on a young woman. We have been investigating the offence for a number of weeks and unfortunately we have not identified a suspect. We continue to investigate and are doing everything we can to secure justice for the victim-survivor.
“Please look at this image carefully. Could you have been in the location on Thursday 31 August? Do you live or work in the area and do you recognise this man?
“We are very interested to speak to the woman and man who helped the victim at the time of the incident. We believe you may hold some key information that could help this investigation and we urge you to get in touch.
“Please share any information or concerns you have with us as it could be the break in the case we are looking for.”
