A woman is in hospital in a serious condition after allegedly being deliberately hit by a car following a row.
Officers were called to Beddington Lane in Sutton, south London, just after 9pm on Monday to reports of a woman being forced into a car following an altercation with a man, the Metropolitan Police said.
The force was later informed by the London Ambulance Service that a woman, believed to be the same person, had been taken to hospital from an address close to the scene of the altercation.
She remains in hospital in a "potentially life-changing" condition, the Met said.
It added: "It is believed the individuals were known to each other. "Inquiries continue and no arrests have been made."
Dave Wightwick, landlord of the Harvest Home on Beddington Lane, told the Sutton and Croydon Guardian the man had deliberately driven at the woman before forcing her into the car.
He said the man had then driven off at about 70mph.
