Releases in error

A prisoner is released in error if they are wrongly discharged from a prison or court when they should have remained in custody, where the prisoner has not deliberately played a part in the error (i.e. the prisoner had no intent of escaping).

Examples include misplaced warrants for imprisonment or remand, recall notices not acted upon, sentence miscalculation or discharging the wrong person on escort.

The data source for this measure is HM prison and probation service annual digest.
