An abscond is an escape that does not involve overcoming a physical security restraint such as that provided by a wall or fence, locks, bolts or bars, a secure vehicle, handcuffs or the direct supervision of staff.

Absconds are monitored to analyse the frequency across the open estate and identify any trends nationally also taking into consideration, the management of risk to the public. It is only possible to abscond from open prison conditions.

The data source for this measure and more detailed information can be found in the HM prison and probation service annual digest publication.
