The Williams Lake RCMP, BC Ambulance and Williams Lake Fire Department responded to a call Wednesday when an unoccupied, parked van rolled down the hill on Seventh Avenue North, striking the Alex Fraser Research Forest building. Police say the person responsible for the vehicle tried to stop it but was unsuccessful. The person was uninjured but distraught and, as a result, was taken to hospital for observation. The van was later towed. There was no cost estimate or description of damage to the vehicle or building at press time.
