Motorists are being urged to come forward with information after a vehicle with two children in the back of it was allegedly carjacked following a police pursuit on the motorway.
Officers say the Toyota was taken from a slip road near the M25's junction with the A3 in Surrey following a brief confrontation with the driver.
Police found the car abandoned - with the children still inside and unharmed - a short time later a couple of miles away in the Whiteley Village area.
With the incident happening near a busy road junction at just before 10am on Tuesday (May 3), police believe it must have been witnessed by a number of motorists.
The drama started after a car travelling clockwise on the M25 between Leatherhead and Wisley failed to stop for police officers.
A short time later a number of people are said to have got out of the car and run off after it stopped at junction 10 of the M25.
One of the occupants is thought to have taken the Toyota, which had stopped on a nearby slip road.
Detective Inspector Pete Howgate says the "dangerous driving" and subsequent actions of the people who were inside the car that failed to stop for police had "put the lives of other road users at risk".
He says it is fortunate that nobody was injured but is appealing for witnesses to come forward "as a matter of urgency".
Anyone with information about the incident is asked to call Surrey Police on 101. Alternatively, Crimestoppers can be contacted anonymously on 0800 555 111.
