The prevalence of mental illness and unmet needs of police custody detainees.

Our findings not only confirm high rates of mental health problems amongst police detainees but also demonstrate their high risk of suicide and high levels of unmet need, especially as regards accommodation. This underscores the need to provide mental health services in police stations, to help identify and resolve these issues at this early stage in the criminal justice system. Extending accommodation capacity to help some arrestees may help to save lives and interrupt cycling through the criminal justice system.
