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".
One victim's lawyer calculates his sentence as one month per sexual assault.
