The Herbert Protocol is a national scheme introduced by the police in partnership with other agencies which encourages carers to compile useful information which could be used in the event of a vulnerable person going missing. I recently found out that this protocol was in operation within the South Yorkshire region, and I think it might be useful for other care givers (esp. those living with/caring for a vulnerable adult) to know about it as well so you can search online to see which other local authorities/regions have the same (or similar) schemes. To find out more about the MET Police guidance on the Herbert Protocol, please follow this link to the MET's website: https://www.met.police.uk/herbertprotocol . You can also download the relevant form to fill in for the person you care for, so that a record of their details is readily available in case the person goes missing.
