WA ambulance volunteer calls in hoax crash A ST John Ambulance volunteer has been charged after he allegedly called in a hoax car crash so he could help with the emergency response. The 39-year-old man is accused of calling triple zero on Sunday, saying one person was trapped in a vehicle after a collision just outside the coal mining town of Collie, south of Perth. A police helicopter, St John Ambulance and the Department of Fire and Emergency Services were deployed, but no crash scene could be found. The man assisted with the search, police say. He has been charged with creating a false belief and is scheduled to appear in the Collie Magistrates Court on August 14. The court will be asked to order the man to repay the costs of the search.
