A former prison officer who was found guilty of nine counts of rape and one of the attempted rape of six different women has been sentenced to 28 years at Hull Crown Court.
Mark Scott, 34, formerly of Daville Close in Hull, was found guilty last month of the offences which dated back to 2005 and stretched over a period of 13 years.
He must serve a custodial sentence of 20 years with an extended licence period of 8 years.
On sentencing Judge recorder Ben Nolan QC said Mark Scott had a "ingrained sense of entitlement to sex on his terms", "a sadistic streak" is a "dangerous man" and that he displayed violence towards the women while committing his crimes.
Detective Sergeant Anneliese Tomlinson from Humberside Police’s Protecting Vulnerable People Unit said the women who came forward in the case should be held in the highest esteem for their bravery and dignity throughout.
