Serial rapist Joseph McCann will serve an extra 10 years behind bars after the Court of Appeal extended his sentence.
McCann, aged 35, was given 33 life sentences and ordered to serve a minimum of 30 years after a two-week long spree saw him attack 11 women and children.
After a trial at the Old Bailey, McCann was convicted of 37 offences.
His cocaine and vodka-fuelled rampage across the country eventually ended when he was apprehended in Congleton on May 6 last year, having climbed up a tree to avoid police officers.
As well as McCann, serial rapist Reynhard Sinaga has also had his prison sentence extended to a minimum of 40 years behind bars.
Sinaga was convicted of 159 sex offences in January.
Solicitor General Michael Ellis had sought whole life terms against the two men but this was rejected in October by a panel of five judges.
Instead the pair both had their minimum terms extended.
Giving the court’s ruling, the Lord Chief Justice Lord Burnett said: “The offending in the cases of McCann and Sinaga, very serious indeed though it is, does not, in our judgment, call for either to receive a whole life tariff.
“This is not to minimise the seriousness of their offending but instead to ensure that the most severe sentence in our jurisdiction is reserved, save exceptionally, either for the most serious cases involving loss of life, or when a substantive plan to murder of similar seriousness is interrupted close to fulfilment.”
The judge said the increased sentence was to reflect the seriousness of the crimes.
He added: “Neither man has shown any remorse and the long-term psychological damage for at least some of the victims in both trials is profound and will only be understood in the years to come.”
The judge said that, whether either man is in fact ever released from prison will be depend on the Parole Board’s assessment of the risk they pose after they have served their minimum jail terms.
