AI-generated summary
Phillip Walton, a 48-year-old with schizophrenia well-managed on clozapine for nearly 20 years, suffered an acute psychotic episode likely precipitated by cannabis use at a circus. After aggressive behaviour requiring police restraint with OC spray and Taser, he was brought to Casino police station. Paramedics conducted a grossly inadequate assessment (45 seconds) without vital signs or mental health evaluation, falsely documented in records as comprehensive. When Phillip became agitated in custody and self-harmed, police removed him from the dock and restrained him prone for 100 seconds. He lost consciousness and suffered cardiac arrest. Autopsy revealed chronic coronary artery disease and elevated clozapine levels. Clinical experts concluded restraint-induced hypoxia precipitated fatal arrhythmia. Key failures: paramedics' failure to perform proper assessment or recognise psychosis risk, inadequate documentation, and police restraint technique in context of cardiopulmonary vulnerability. Training on prone restraint risks existed but application failed.

Error types
Clinical conditions
Contributing factors
- cannabis-induced acute psychosis precipitating aggressive behaviour
- inadequate paramedic assessment failing to identify mental health crisis
- false and inaccurate medical documentation by paramedics
- police restraint causing hypoxia and impeding breathing
- underlying chronic coronary artery disease with focal narrowing of coronary arteries
- elevated clozapine levels potentially contributory to arrhythmia risk
- obesity and myocardial fibrosis predisposing to sudden cardiac death
- restraint positioning with knee placement on head/upper neck area
Coroner's recommendations
- No formal recommendation made regarding prone restraint policy training as training on risks of prone restraint and positional asphyxia was already provided to police officers
- Defibrillator to be installed at Casino police station (already implemented as of inquest date)
