There are two types of information that a NHW scheme may need to share.
Further information about the sharing of both types of information can be found in the ACPO Policing and Watch Schemes Guidance on Information Sharing (August 2001).
The guidance is currently being revised. ACPO has just finished negotiating with the ICO on this guidance. The updated version will be available on this webpage later in 2008.
