Three people have died after a car crashed off the road and struck a tree, leaving the roof torn open.
The high-powered vehicle crashed off Stoneville Road just before 9am on Saturday in Stoneville, east of Perth.
The three adult occupants in the car died at the scene.
'I came around the corner and saw the car there wedged between two trees,' a witness told 9News.
'It was pretty serious. The roof was semi ripped open. It was pretty mangled and it's an old car too, so it's made out of proper steel.
'It was wedged inside two trees - only 1.5 - maybe 2m wide. A tree was on top of it as well.
'A bobcat was already here getting ready to pull it off, just trying to open it up for the emergency services as best they could for when they got here.'
Some passersby attempted to help the occupants inside the car.

Another witness said the car had 'careened' past her.
'I think they overcorrected and ended up sideways pinned between two trees,' she said.
Police blocked off the road for hours as first responders dealt with the aftermath.
It is understood the area of Stoneville Road where the tragedy took place has a speed limit of 80 km/h.
Officers from the Major Crash Unit are continuing their investigation.
