The video, shown during a bail hearing at the Perth Magistrates Court, captures Dunn's Ford Everest travelling on Franklin Road, a single-lane carriageway in Perth's north. The song 'The Sign' by Ace of Base is audible on the radio as the vehicle accelerates. Dunn was charged with aggravated dangerous driving causing grievous bodily harm, four counts of aggravated dangerous driving causing bodily harm, and attempting to pervert the course of justice.
Dunn's lawyer applied for bail, raising concerns about his client's mental health. Police opposed the application and presented the footage to the court. Dunn was remanded in custody following the hearing.
The court heard that Dunn was working for Rescue Recovery 1, a private company that provides event medical, ambulance, and first aid training services. He had been called by one of his crews attending an event in Jarrahdale to relieve them while they transported a patient to hospital.
