Police have released an image in their hunt for a man who allegedly sexually assaulted a 12-year-old schoolboy after luring him into a house in north-west London.

Detectives say the victim was approached by a man wheeling a bicycle in Willesden Green at about 3.50pm on Wednesday, January 11.

The man spoke to the boy on Park Avenue before persuading him to go to a nearby home in Griffin Close, where he carried out the alleged assault.

Investigating officers have now released a photo of a man they want to track down and question over the incident.

He is described a south-east Asian, in his mid 20s, around 5 ft 4 ins tall and was wearing a light green long-sleeved top and grey trousers on the day of the assault.

Detective Inspector Christine Edgar, who is leading the investigation by the Sexual Offences, Exploitation and Child Abuse Command, said:

“We are appealing for anyone who recognises, or thinks they recognise, the man in the images we’ve released, to contact us.

“We are also continuing to appeal for witnesses, or anyone in or around the areas of Park Avenue and Griffin Close, that saw the man with a boy, to also contact us.
