Somebody overdosed on Weetabix...

Looks lie a fairly steep hill. Maybe brake or handbrake failure?

Surely brake failure?
Good effort to get away with only five injured.

Brake failure is very rare due to the way the systems operate - if there was a true failure in the system then in most cases the brakes would come on. Its possible but I would be looking at medical issue or human error before mechanical failure.

Brake failure would be highly unusual - any 'failure' in the brakes results in them being jammed on by the spring brake.

PSVs are tested and monitoed to a really high level (much more than our cars) so proper catastrophic failure to cuase something like that is rare.

Left the handbrake off?
Has that Mercedes been used to try to squeeze it against the wall to bring it to rest

I believe that's a well respected coach operator and mechanical failure is quite unlikely. Similar issues are often health related.

Might have just collected it on the way down?
