An exclusive Granada Reports investigation has revealed the shocking number of killings carried out by criminals who've been released early from prison.
In one part of Greater Manchester alone, over the past three years, three offenders have committed murder or manslaughter after they'd been released into the community to serve the rest of their sentence on licence.
The families of two of those victims claim they've been failed by the system that was supposed to protect them.
The Probation Service Union says their members have passed breaking point and mistakes are being made.
This exclusive investigation comes from our correspondent, Matt O'Donoghue.
