There was a “repeated failure” by probation officers to recall serial rapist Joseph McCann to prison, a report has revealed.
McCann was given 33 life sentences after being convicted of a series of offences against 11 women and children.
There were eight opportunities to recall McCann after he was freed from jail for a burglary offence, the Serious Further Offences report said.
Justice Secretary Robert Buckland promised an independent review.
A summary of the report said McCann should have been kept in jail at least until the Parole Board was satisfied it was safe to let him out.
It says there were eight occasions when this process – called “recall” – was considered.
“The most significant practice failure was the repeated failure to recall Joseph McCann or to reflect critically on earlier decisions not to recall him, in the face of both court and prison staff communicating their concerns,” the report said.
It disclosed that in 2011, when McCann was in prison for burglary, police shared information dating back to 2003 and suggesting McCann “might pose a risk of sexual harm and exploitation to teenage girls”.
The prison holding McCann had also intercepted two sets of letters from McCann with “disturbing contents… some of this content indicated he posed a risk of sexual harm.”
The Ministry of Justice, which carried out the review, said the chief inspector of probation Justin Russell will be asked to carry out an independent review of the National Probation Service’s management of McCann and how the process of recalling offenders to prison is working.
The Attorney General also said he has referred McCann’s sentence to the Court of Appeal under the Unduly Lenient Sentence scheme.
This hearing will take place on 25 March.
