  • Organic emergency (hypoxia, hypoglycaemia, head injury, encephalitis, severe intoxication) labelled as 'behaviour' and diverted only to custody
  • Police cell used as default place of safety when a health facility is available and safe
  • Inventing Mental Health Act section numbers or universal detention time limits across jurisdictions
  • Named victim, weapons, or imminent violence at scene without simultaneous safety, de-escalation, and protective plan
  • Releasing a high-risk person after police conveyance without specialist assessment or crisis follow-up

The one-line answer

Police liaison in psychiatry is structured multi-agency work so that community behavioural-health crises are met with safety, de-escalation, clinical assessment, and least-restrictive care — not automatic arrest or default custody. Community emergency detention is a time-limited pathway to assessment, distinct from criminal arrest and from longer civil commitment. Prefer a health place of safety over a police cell when available and safe. Landmark models are CIT (Memphis), co-responder or street triage, and tri-response. Name England and Wales s135 and s136 when discussing that jurisdiction; for everywhere else, state local emergency powers under the current statute and never invent a section number.[1][11][13][15]

Meet the patient

A 31-year-old man with known schizophrenia has stopped his depot. He is standing on a suburban footbridge at midnight, shouting that he is being followed. A member of the public has called the police. He is not violent, but he is frightened and he is close to the edge of the road.[1][11]

Two services arrive at the same scene with two different toolkits. The fellowship question is not which one takes him — it is whether the response was designed to keep him out of custody, into assessment, and alive. That design is what this topic teaches.[2][11]
