A teenage boy was struck by a car in front of his two horrified sisters after the driver mounted a kerb and travelled 40m along a footpath in Willetton this afternoon.
The 14-year-old was taken to Princess Margaret Hospital with head injuries after a silver hatchback ploughed into him outside Burrendah primary school about 2pm.
It is understood the boy was conscious when bystanders rushed to help him until paramedics arrived.
There were no skid marks on the footpath and police are investigating what caused the driver to veer off the road.
The driver stopped at the scene and it is understood there is no evidence he had alcohol or drugs in his system.
It is believed the boy, a Willetton high school student, was on his way to play basketball when he was hit as he walked on a footpath on Pinetree Gully Road.
He is in a serious but stable condition in hospital, with his parents and sisters by his side.
