A woman removed her father's prosthetic leg before mounting him and biting his face in a vicious attack. Helena Coyne, who had been consuming alcohol, also kicked her father's dog during the horrific assault.
The 37 year old, from Withington in Manchester, was brought before a court following the incident on 15 August this year. She avoided custody with a community order after admitting occasioning actual bodily harm, Manchester Evening News reports.
A judge told her: "This was a mean, brutal and humiliating assault which you committed on your own father."
Prosecuting, Gavin Howie earlier told Manchester Crown Court that Coyne's father is a double amputee who lives with his dog. He had 'several fingers amputated' after contracting sepsis, the court heard.
"He lives in a ground floor flat specially adapted for his needs," Mr Howie added. "A number of family members were visiting him at home on the day of the incident, including the defendant."
"Everyone was said to be in good spirits. The guests left at around 8pm, apart from the defendant, whose attitude was said to change towards her father."
Coyne became 'irate and angry' towards her father because he had sent her daughter - his granddaughter - money. "She did not like the idea that he was providing for her," Mr Howie added.
"While he was sat on the sofa, she held him by his prosthetic leg - which was pulled off - and pulled him onto the floor. She then got on top of him and bit his left cheek, breaking the skin, and held it there for some 15 seconds. He tried to push her off but her grip was too strong."
The court heard that the victim's dog JJ attempted to defend him, before Coyne kicked the animal in the face. She departed, and subsequently her father contacted the police.
He received treatment for his injuries, which were documented with photographs for evidence. Later, Coyne phoned the police and confessed.
She was arrested at a hostel.
When questioned by the police, she declined legal representation and admitted her actions to the officers. Judge Paul Lawton was informed that Coyne has seven previous convictions for 11 offences dating back to 2001 - including public disorder and drug offences.
In mitigation, Zahra Khan made no representations to the court, except to indicate that her client was 'actively seeking' mental health support.
"This was a mean, brutal and humiliating assault which you committed on your own father," said Judge Lawton. "The day was said to be a happy afternoon with everybody in good spirits. But when everyone else had left, you became increasingly irrational and irate over something entirely trivial.
"Your father was particularly vulnerable due to his condition. You pulled him to the floor, climbed on top of him and bit him. It was an utterly humiliating assault.
"You quickly regretted your behaviour, calling the police and immediately confessing to what you did. That is what stops me from imposing an immediate custodial sentence.
"It is accepted that you were in drink at the time. You deny having an alcohol dependency or any alcohol issues. You have been homeless but you now have stable accommodation.
"There is a clear prospect of your rehabilitation. I believe if I were to impose a custodial sentence it would be completely destructive and not be in the public interest."
Coyne, of Wilmslow Road, Withington, was handed an 18-month community order, instructed to participate in the 'Building Choices' programme and ordered to complete 25 rehabilitation activity days.
The charge of causing unnecessary harm to an animal was permitted to lie on file. The judge also imposed an alcohol abstinence monitoring requirement.
"You need to grasp this opportunity with both hands," he told her. "If you do not comply, you will be back before me and there will be little choice but to send you to prison."
