"David Blunkett is set to launch a year-long pilot study of his plan to track offenders by satellite. The system will allow police to monitor the movements of the tagged person 24 hours a day, and will give their location to within just a few metres
The scheme is designed for those who have served part of a custodial sentence and have been released, and those who have been given a curfew, for example. The idea is that the tracking devices would be fitted to people that police and probation officers feel are likely to contact their victims, or break the terms of their release from jail: sex-offenders, wife beaters and persistent offenders, for example."
