Police have cordoned off a road in Harlesden after an apparent crash following which an air ambulance landed.
Church Road is shut after the collision at around 6pm apparently involving a moped after which reports suggest there was some kind of altercation.
Four ambulances are said to have attended and an air ambulance landed.
Images from the scene show an extensive police cordon covering a significant section of the road, a scooter, some strewn rubbish, and a section of grass behind a wall by the road.
The scooter has a box on the back, suggesting it might have been used for deliveries.
Other images show police dogs searching the grassy area behind the wall.
Onlookers say an injured person was taken away in an ambulance which drove off without its flashing lights on.
My London has contacted the Metropolitan Police, London Ambulance Service and London’s Air Ambulance for more information.
