Progress made at Wetherby YOI

We've been given exclusive access to a young offenders unit which two years ago drew damning criticism from prison inspectors who said they "feared for all its inmates."

In 2012 Wetherby Young Offenders Unit was censured for the vulnerability of the young people held there, but a new report shows progress has been made.

Although there's still concerns about group attacks and self-harming, the unit is working with its inmates to improve standards.
