Leslie Jackson left his victim with 54 separate injuries after attacking her at a property in Aberdeen on July 30, 2022.
Despite a young child being present, the 38-year-old repeatedly punched the woman in the face, rendering her unconscious.
After she regained consciousness, he attempted to strangle her and hit her repeatedly with a knife.
The abuser then held the weapon across the woman’s mouth, threatening to give her a ‘Chelsea smile’.
The following afternoon, the victim managed to escape by jumping from a ground floor window with a makeshift tourniquet wrapped round her leg.
Jackson appeared at the High Court in Glasgow on 8 May 2024 where he admitted a charge of abduction, assault to severe injury, permanent disfigurement, and danger of life.
He was given an extended sentence of 12 years with eight in custody at the High Court in Glasgow on June 5, 2024.
Moira Orr, who leads on homicide and major crime for the Crown Office and Procurator Fiscal Service, said:
“Our thoughts and best wishes remain with the brave victim of Leslie Jackson as well as her loved ones following this ordeal.
“We recognise that this type of violence can inflict lasting trauma on survivors and their extended families, especially on children and young people who may witness it.
“The violent offending committed by Jackson is horrific and abhorrent. He will now have to face the consequences of his actions.
“We are committed to the prosecution of crimes such as this, which are an unacceptable blight on our society.
“I would encourage all victims or witnesses of similar offending to come forward, report their experiences and seek support.”
