A serial rapist attacked 11 victims in a two-week rampage after being freed from prison by mistake.
Joseph McCann, 34, was yesterday found guilty of kidnapping, raping and sexually assaulting women and children aged between 11 and 71.
McCann, who is facing life in prison, will be sentenced on Monday.
Dr Jo Farrar, the head of the prisons and probation service, issued an unprecedented and “unreserved apology” after it emerged that McCann had wrongly been let out of prison shortly before his rampage.
On Friday retired judge who tried to protect the public from McCann a decade ago criticised the string of “clear errors” that led to his release.
Senior politicians led calls for an independent review into “shocking failures” surrounding the case.
Over two weeks in April and May, 34-year-old McCann snatched victims off the street and subjected them to barbaric sexual assaults at knifepoint.
His victims included a 71-year-old woman and an 11-year-old boy.
