The 51-seat coach from Aintree in Merseyside was returning from Bestival on the Isle of Wight
Three people were killed and a number of others seriously injured when a coach returning from a festival on the Isle of Wight overturned after crashing into a tree near a tunnel in Surrey.
The 51-seat coach was going north on the A3 when the crash happened near the Hindhead Tunnel at 23:50 BST on Monday.
The coach from Merseyside left the carriageway between the tunnel and the Thursley exit and hit a tree.
Injured passengers have been taken to a number of different hospitals.
Three people were declared dead at the scene.
A fourth person was airlifted to Southampton General Hospital with life-changing injuries, said police.
No other vehicles are thought to have been involved in the crash.
Insp Richard Mallett said the vehicle had suffered a “significant impact”.
“I understand the road was dry. We cannot see any reason that the road conditions would have had any effect on what occurred,” he said.
