The Clinic for Forensic Psychiatry at LVR-Klinikum Essen (North Rhine-Westphalia, Germany) has a total of 54 places. The facility is used for temporary placement in accordance with Section 126a of the Code of Criminal Procedure. Accordingly, patients are accommodated here if there are urgent reasons to believe that they have committed an unlawful act in a state of incapacity.
