Step Two: Face to face meeting - Police may run checks with other agencies including the prison service, the probation and social services.
Step Three: Multi agency meeting - police meet other safeguarding agencies (such as the probation service, prison service, social services). They decide whether disclosure is lawful, necessary and proportionate to protect a person.
