John Worboys is a cab driver thought to have sexually assaulted at least 100 victims and convicted on 19 counts in 2009. But he's getting out of jail after only 8 years, having nailed it as his first parole hearing.
He was convicted of one rape, five sexual assaults, one attempted assault and 12 drugging charges.
As well as being ordered to serve at least eight years, Worboys was given an indeterminate sentence, meaning he could be kept in prison as for as long as he was deemed to remain a danger to the public.
In 2010 Worboys had an appeal against his conviction thrown out by the Court of Appeal, where Lord Justice Moses labelled his offences as "appalling".
They didn't even bother to tell his victims.
The chairman of the Parole Board has apologised "unreservedly" after some victims of sex attacker John Worboys were not told about his release.
Nick Hardwick said hearing the decision must have been "horrible" for the women but the board was "confident" 60-year-old Worboys would not reoffend.
Former black-cab driver Worboys is believed to have carried out more than 100 rapes and sexual assaults on women.
One lawyer, quoted by the BBC, calculates his sentence as one month per sexual assault.
