The number of sex offenders and violent criminals being monitored by police in Derbyshire has risen by 10 per cent in the last 12 months.
Sex offender numbers have gone up from 977 to 1,046 - a rise of 7.6 per cent.
The number of violent or dangerous criminals - who have committed crimes including assault, robbery or wounding - being monitored has risen by 23.3 per cent to 284.
All of the offenders are subject to multi-agency public protection arrangements - MAPPA - which keep tabs on their movements in an attempt to prevent them re-offending.
Derbyshire Police assistant chief constable Martyn Bates said: “Safeguarding the public from violent and sexual crime continues to be one of the highest priorities for agencies across Derbyshire.
“Working together through Multi-Agency Public Protection Arrangements to manage offenders convicted of such crimes is vitally important.
“The crimes these offenders are responsible for greatly affect the lives of victims, their friends and families, and cause fear in local communities.
“While it is never possible to eliminate that risk MAPPA aims to ensure all steps are taken to reduce risk of further serious harm.”
