This will include offenders who are in custody and those in the community, and those who are currently required to be supervised and those who are not. It also contained 3,906 persons categorised as being a “Violent Offender” and a total of 14,647 persons recorded as being managed as a “High Risk” or “Very High Risk” person.
It should be noted that ViSOR is a live system used by the police, and is currently subject to a national roll-out to the National Offender Management Service. As such, it does not yet contain all violent offenders or other sexual offenders.

ViSOR is a web-based operational management system that is in continuous use. It is not possible to provide a meaningful statistic relating to the number of times the database has been accessed.
