A total of 21 2.0 HDi Combi 6 models were ordered as part of a multi-agency programme trial, which also involved the Crown Prosecution Service, the National Offender Management Service and police forces nationwide.
The standard Citroëns have been fitted with a modular, slide-in, two person cell unit capable of carrying two offenders as well as court enforcement officers.
They were developed by Citroën in conjunction with Kinetic Special Vehicles. The 21 trial vehicles are based at courts throughout the north west of England.
If the trial proves successful, the vehicles will be rolled out to courts and police forces throughout England and Wales from April next year.
Police inspector Kevin Keen, of the National Enforcement Service Programme, said: ‘The vehicles will make it easier for court enforcement officers, be more cost-efficient in operation and provide greater security for the carriage of offenders.’
