A 45-year-old WA Police homicide detective took his own life early Monday morning at the Northbridge headquarters in Perth. The officer had recently returned from a family event overseas and was stopped at Perth's International Airport, although it's unclear if this incident is related to his death. WA Police Commissioner Col Blanch emphasized the challenging nature of police work and the importance of mental health support, which is being provided to the officer's family and colleagues. WA Police Union president Paul Gale mentioned that the loss has deeply affected the policing community across Australia. The death is being treated as non-suspicious, and a report is being prepared for the coroner.
