One in five murders is committed by prisoners released on parole, shocking figures show.
The dramatic 63% increase in homicides by ex-inmates since 2015 prompted criticism of the failing probation service.
The figures have led to demands for urgent investment in the service, still reeling from disastrous reforms that placed some parts in the hands of private companies.
The Mirror revealed earlier this year that the Government planned to renationalise probation as ministers accepted their experiment had failed.
Reforms introduced by Chris Grayling when he was Justice Secretary have cost taxpayers almost £500m and led to an increase in murders committed by criminals.
Figures show that at the end of March 2017, 112 of the 613 killings were by people on parole.
The following year showed an increase in murders to 695, excluding 31 terror attack victims, with 114 deaths by those on probation.
Harry Fletcher, of the Victims’ Rights Campaign, said: “These are shocking statistics - a rise of over 60 per cent where the alleged perpetrator is on parole or supervision defies belief.
“Yet again, victims are ignored by the criminal justice system.”
Plaid Cymru MP Liz Saville-Roberts, who obtained the figures, added: “This is an extremely worrying development. The Ministry of Justice must implement its new reforms without delay.”
An attacker who slipped through the net was Leroy Campbell, 57, who was released from prison four months prior to raping and murdering nurse Lisa Skidmore, 37, in her West Midlands home in November 2016.
He had been watching her for weeks - after chillingly telling his probation officer that he ‘felt like raping’ someone again.
Marvyn Iheanacho, 41, flew into a violent rage and beat his girlfriend’s son, five, to death after the youngster lost his shoe in a South London park.
He had a catalogue of convictions for violence.
