Thousands of crimes were committed by previous offenders in Scarborough last year, figures show.
The news comes as the probation watchdog says criminals sentenced to short prison terms are locked in a “merry-go-round” that leaves the public at risk and costs billions of pounds a year.
Ministry of Justice data shows that, of the 1,479 offenders in Scarborough who were released from prison, received a non-custodial conviction at court, or were cautioned by police between July 2016 and June 2017, 555 went on to reoffend within a year – 38%.
Between them, they committed 2,521 new offences.
They had each committed an average of 25.1 crimes previously.
The rate of reoffending was even higher among juvenile offenders – 56 of the 100 under-18s (56%) went on to commit another crime within a year of being released from custody, given a non-custodial sentence or cautioned.
A report from HM Inspectorate of Probation highlighted shortcomings in the system for managing offenders in England and Wales.
It includes figures showing 64% of adults released from custodial terms of less than 12 months re-offended within a year, committing crime estimated to cost the economy £7 billion to £10 billion per year.
Earlier this year, Justice Secretary David Gauke said there was a “very strong case” for abolishing sentences of six months or less, with some exceptions, such as for violent or sexual crimes.
Chief Inspector of Probation Dame Glenys Stacey said that such a move was “unlikely to be effective without other changes”.
From 2015, every criminal given a jail term became subject to statutory supervision and rehabilitation upon release into the community.
Prior to the change, which was designed to reduce re-offending, convicts who had served less than one year did not have to be supervised by probation services.
But the inspection report found there had been “no tangible reduction” in re-offending.
Re-offending rates varied significantly between types of crime for the July 2016 to June 2017 cohort. While figures are not available at a local authority level, across Yorkshire and The Humber:
Theft offences: 56% of 8,124 offenders committed a crime within a year of being released from custody, given a non-custodial sentence or cautioned (compared to 52% across England and Wales)
Drug offences: 22% of 3,699 offenders (England and Wales: 25%)
Violence against the person: 27% of 3,196 offenders (England and Wales: 25%)
Possession of weapons: 35% of 947 offenders (England and Wales: 31%)
Sexual offences: 9% of 645 offenders (England and Wales: 14%)
Re-offending rates have remained largely steady over recent years in Scarborough, varying from a low of 36% between July 2008 and June 2009 to 40% from July 2014 to June 2015.
Responding to the HM Inspectorate of Probation report, Frances Crook, chief executive of the Howard League for Penal Reform, said: “Chris Grayling’s decision to extend post-release supervision and place it in the hands of private companies has ended in failure, as the Howard League and others warned it would.
“It has not made the public any safer, but it has trapped tens of thousands of people in the criminal justice system for even longer than necessary.”
