    Lack of established links between police Safeguarding teams and NHS mental health teams

    Wider context from the report

    “During the course of the inquest, the local MPS investigation by Directorate of Professional Standards reported the view of the Central Mental Health Team that Sexual Offences Investigation Trained officers require further training in mental health. ████████ the investigating officer, gave evidence that it would be beneficial to have a mental health single point of contact within the local mental health team who could be contacted for non-urgent advice by Safeguarding Teams concerning victims that they are most concerned about. The investigation found no misconduct by officers, who provided a good level of care and support. It appears that the police Safeguarding team have no established links with NHS MH team and that referral to a Crisis Resolution and Home Treatment Team depends on an officer recognising the need was urgent, which may be a difficult judgment for officers, without professional mental health advice. ”

    PFD Monitor interpretation

    Employ two Metropolitan Police officers within main SLaM hospital sites to provide information, advice and support and liaise with borough safeguarding officers.

    Verbatim wording from the response

    “Mental Health Support to Metropolitan Police Officers ████████ identified that the Metropolitan Police do not have a Safeguarding Adult Team, however, there are safeguarding strands attached to all 12 of the Borough Command Units. South London & Maudsley NHS Trust Foundation Trust employ two full time Metropolitan Police officers who work within our main hospital sites and liaise on a three monthly basis with the borough command safeguarding officers who all have mental health knowledge and experience. The officers employed within our mental health trust would usually act as a conduit for information, advice and support within our service but also their fellow officers in the borough command units”

    PFD Monitor interpretation

    Failure to exchange relevant information between Police and Mental Health Services

    Wider context from the report

    “1. At the time of arrest of Mr Cairns, the Police were aware of his assessment under Section 136 of the Mental Health Act the previous day. The Custody Nurse had contacted the Crisis Team to obtain information regarding the 136 assessment which was duly given by the Mental Health Team. However, there was no reciprocal exchange of information and the Mental Health Team were not informed that Mr Cairns had been arrested with regards to Threats to Kill his partner. 2. At the conclusion of the Inquest and after all the evidence was heard, it came to light that there was in existence a policy for mutual sharing of information between the Police and Mental Health Services if each respective organisation requested information from the other. 3. This document was not disclosed prior to the Inquest or during the Inquest itself and it would have been critical to ask witnesses from the Police and Mental Health Services about their knowledge of this document. ”
