“When someone goes missing it is a very stressful time for everyone involved. We hope that the Herbert Protocol will provide the families of people living with Dementia some reassurance.
Tim Benson from the Alzheimer’s Society said: “The Herbert Protocol is a tried and tested system to support people who are lost due to cognitive problems. Its introduction into Derbyshire is very welcome.
“Derbyshire Constabulary has carried out extensive consultation and discussion with stakeholders to implement the system. This sound base should get the protocol off to a good start. It deserves the support of all those involved.”
