A 15-year-old girl was sexually assaulted in an attack in east London.
Police probing the sex attack, which happened at a house in Eastern Avenue, Ilford, have now released a photo of a man they would like to speak to.
Detectives are urging anyone who recognises the man to come forward with information as it could help with the investigation.
DC Monir Nainia, who is leading the investigation, said: "I am appealing to anyone who believes they recognise the man in the image to contact us.
“Similarly, if the person in the image recognises themselves, they should also contact us.
"All our enquiries to identify the man in the image have not so far resulted in a positive identification, so we are hoping the public can help us."
Anyone who can identify the man, or who has other information that may assist the investigation, is urged to call the East Area Safeguarding team on 101, or via Twitter @MetCC. To give information anonymously call Crimestoppers on 0800 555 111.
