In the U.K (speciffically England) if someone experiencing a mental health crisis and non-specific suicidal thoughts attends A&E seeking support and coping strategies, whether that is advice or medication, could the A&E department apprehend them and prevent them from leaving for any period of time against their will?
What are the thresholds that must be proven or established to justify having someone kept for mental health reasons against their will?
Must their threat of harm to others or self be somewhat immediate or is a nebulous, distant thought or fear sufficient?
What other requirements must be met?
