Police have named the 18-year-old man who died after being shot in Tottenham as Andre Salmon.
Police and paramedics rushed to Constable Crescent at 5pm on Monday after Mr Salmon crashed his moped into a parked car.
Despite their best efforts he was pronounced dead at the scene.
Police believe the victim was riding the moped along Stamford Road when he was shot by a suspect riding an electric scooter.
“Following the incident the victim continued along Stamford Road, turning left into Constable Crescent, where due to his injury his moped collided with a parked car and he collapsed,” a Met spokesperson said.
The suspect - described as a black man in his late teens or early twenties - is then understood to have made off from Stamford Road.
No arrests have been made yet.
Detective Chief Inspector Dave Whellams described the daylight shooting in a residential area as “shocking”, and urged anyone with information to come forward.
