A 97-year-old father attacked by his son with a hammer and saw told a court he did not want to see his son jailed.
But Stefan Martens from St Annes will be detained for 14 years after being found guilty of what a judge called a ‘ferocious’ attack.
A judge at Preston Crown court imposed what is known as a ‘hybrid order’ on Martens who will be jailed as well as being sent to a psychiatric unit for treatment.
The victim, Janek Martens, said he did not want his son to be punished or sent to prison.
Stefan Martens, who had devoted half his life to caring for his father, a Second World War Spitfire pilot, had a severe depressive illness where the burden of looking after his parent got on top of him.
He struck his father with a hammer and cut his throat with saw. Despite suffering a heart attack, Mr Martens survived the horrific attack in March at the house they shared on Blackpool Road North, St Annes.
Mr Martens Snr is now in a care home.
His 58-year-old son denied attempted murder, but a jury convicted him following a trial in September. He had admitted wounding with intent.
The trial heard that after carrying out his attack, Stefan Martens rang the emergency services to say: “I think I have just killed my father”.
He went on to add: “I just lost it this morning and attacked him. He’s a bit of a mess”.
Paramedics found the father lying on a rear dining room floor, with blood all over his face and arms.
He had a four centimetre cut to the right of his a neck, and an arm injury.
Mr Martens Snr also had a fracture to the cartilage of his voice box.
He declined to make a statement to police and did not support the prosecution, telling officers he could remember nothing of the incident.
Chris Hudson, defending, said Martens had devoted the second half of his life to looking after his father. In the years leading up to the offence he had no other interests or outlet.
Marten’s father had told the court: “I don’t think Stefan should be punished at all.
“What happened was a pure accident. I love Stefan and I always will. I don’t want him to go to prison.”
