A 12-year-old schoolboy was allegedly lured into a house and sexually assaulted in Willesden Green.

Detectives are appealing for witnesses after the boy claimed he was approached by a man on Wednesday afternoon in Park Avenue.

The man is believed to have persuaded the schoolboy to go to a nearby address with him, in Griffin Close, where he then assaulted him.

The man has been described as south-east Asian, aged in his 20s and around five foot four inches tall.

He was wearing a grey coloured beanie hat, a light green top, grey trousers and he was pushing a bicycle.

Police are appealing for information from anyone who may have seen a man matching this description in the area at the time of the attack, which took place just after 3.50pm.
