A 16-year-old cyclist is fighting for his life after a suspected double hit-and-run crash in south London.
The boy was riding along Streatham High Road on Friday night when he was hit by two cars in succession, police believe.
He was found critically injured at the scene and taken to hospital, where he remains in a life-threatening condition.
Officers believe the boy had been cycling on the High Road just ater 11.15pm when he was in collision with a car.
Seconds later, he was struck by a second car travelling close behind, police believe.
The drivers of both cars failed to stop at the scene.
Officers investigated and arrested two men at separate locations in the local area. The men - both aged in their 20s – remain in custody at south London police stations.
It is not thought that the two drivers were known to each other, but enquiries continue to establish the full circumstances.
The investigation is being led by detectives from the Roads and Transport Policing Command.
Anyone with information or dashcam footage can call the Serious Collision Investigation Unit at Catford on 020 8285 1574.
