Surrey Police Inspector Richard Mallett has given more details about the A3 coach crash, saying that police will study nearby CCTV footage.
Speaking on Sky News, he said:
We would be grateful for any witnesses.
We need to make sure we get the people out properly before we can broaden the investigation. We are reasonably confident that the driver is still in the vehicle.
CCTV will be looked at.
We have a couple of witnesses which we've spoken to.
It's still going to be a considerable amount of time [before all bodies can be removed.
Every survivor was taken to hospital, after that they were taken to a local reception centre, and some were taken home.
