A 40-year-old man from Northampton has been arrested on suspicion of dangerous driving after two young children suffered serious injuries in a car crash in Milton Keynes.
Thames Valley Police officers were called to Broughton Road at 3.35pm on Sunday after a black Audi A4, coming from the direction of the village of Salford, overturned.
One passenger, an 11-year-old boy, sustained life-threatening head injuries after he was thrown from the vehicle. He was airlifted to the John Radcliffe Hospital where he remains in a critical but stable condition.
Another passenger, a 10-year-old girl, sustained serious arm injuries, which are not believed to be life-threatening. She was taken by ambulance to Milton Keynes General Hospital.
The driver of the vehicle was uninjured.
A man has been arrested on suspicion of driving while over the prescribed alcohol limit and on suspicion of causing serious injury by dangerous driving. He has been released on bail until January 31.
PC Sian Pringle, from the Serious Collision Investigation Unit, said: “I would like to speak to anyone with any information about the collision, or who saw what happened, or anyone who saw the Audi being driven prior to the collision.
“I would also particularly like to speak to a cyclist who was riding along the road at around the time of the collision, who may have witnessed the incident.”
If anyone has any information about the collision call the 24-hour Thames Valley Police enquiry centre on 101.
