Families of 17 justice campaigns - for murder victims or those who died following police contact - will be informed on what information Scotland Yard held about them.
Derbyshire Chief Constable Mick Creedon, who led the inquiry, said:
Operation Herne has identified emerging evidence that in addition to the Stephen Lawrence Campaign, a number of other justice campagins have been mentioned within SDS records. Seventeen such justice campaigns have been identified so far.
These range between 1970 and 2005, and are as a result of deaths in police custdoy, following police contact and the victims of murders.
It is the intention of Chief Constable Creedon and Operation Herne to inform all of the families involved and share, where possible, the knowledge and information held.
