Offences committed in custody are more serious because they undermine the fundamental need for control and order which is necessary for the running of prisons and maintaining safety.
Generally the sentence for the new offence will be consecutive to the sentence being served as it will have arisen out of an unrelated incident. The court must have regard to the totality of the offender’s criminality when passing the second sentence, to ensure that the total sentence to be served is just and proportionate. Refer to the Totality guideline for detailed guidance.
Care should be taken to avoid double counting matters taken into account when considering previous convictions.
