A breast surgeon who carried out needless operations and left one patient looking like a "car crash victim" has had his 15-year jail sentence increased to 20 years.
Ian Paterson was ordered to serve extra time behind bars by the Court of Appeal after judges ruled his original sentence was "unduly lenient".
Paterson, 59, from Altrincham, Greater Manchester, was convicted of wounding offences against 10 patients in April.
Since then hundreds more have come forward and are now seeking compensation.
The disgraced surgeon's motive remains unclear, but prosecutors said he may have carried out the unnecessary procedures in a bid to boost his earnings.
The new ruling came after the sentence was referred for review by Solicitor General Robert Buckland.
After the ruling, Mr Buckland said: "Throughout our lives we are told and expected to trust doctors.
"Paterson woefully abused that trust - he deliberately preyed on people's worst fears and then mutilated them on the operating table.
"This is a truly sickening crime and my thoughts are with the victims and their families. I hope the increased sentence will help bring some closure for them."
During his trial, victims told the court Paterson's crimes had left them in constant pain and struggling to trust medical professionals.
