Three young men were killed in Brent Cross after their car crashed into a pedestrian bridge.
Emergency services were called to Staples Corner retail park shortly before 11.30pm last night (April 15).
Five men, all believed to be aged in their early 20s, were found at the scene.
Three were pronounced dead, while the other two were taken to hospital by London Ambulance Service (LAS).
One man is in a critical condition while the other has injuries not thought to be life-threatening.
London Fire Brigade has confirmed that one of its fire rescue units, which can help with cutting after crashes, attended the scene.
A spokesperson said that a car had “collided with a pedestrian overbridge”, and that two fire engines were sent to the scene alongside the rescue unit.
The incident was over for the Hendon and Wembley firefighters shortly after 1am.

Anyone who witnessed the incident but has not yet spoken with police is asked to call 101, quoting reference 7502/14april.
