Police are investigating a collision in Flesherton, north of Mount Forest, which ended with a school bus crashing into a house.

The bus was parked outside its driver’s home on Napoleon Street on Monday night when it somehow started moving.

Ashley Van Der Meulen and her son were getting ready for trick-or-treating when she heard her neighbour yelling her name.

“My next door neighbour was screaming across the yard to get out of the house and my boyfriend looked over and a bus was coming barrelling at the house and I just grabbed my son and got out.”

Neighbours report seeing a bus roll across the road and through the front yard of a neighbouring property, before hitting a house.

No injuries were reported.
