The police say they are keeping an open mind on the cause of this accident. Road conditions and the weather were both good when the coach veered off the dual carriageway and onto the embankment. Police are now trying to collect every piece of evidence from the scene.
One thing they will be looking at is whether there were more people on board the coach then there should have been. It was designed to carry 51 passengers and one driver, but we know that three people were killed, and 50 passengers were taken from the site to the hospital.
The three who were killed, haven't yet been officially named but we do understand that the driver was Colin Daulby, a man in his early 60s from Warrington. The other two people who have been killed, we understand were festival-goers, both in their 20s.
