A man has been locked up after turning up at the home of his ex girlfriends father and attacking him.
Newcastle Crown Court heard Scott Atkinson, 30, had not seen the victim for 22 months when he knocked on his front door and threw a punch at him.
The victim, who suffered health problems, was unable to move out of the way and Atkinson, of Frobisher Street, Hebburn, swung at him again.
When he shouted "stop" Atkinson continued punching him, climbed on top of him and bit him.
The victim said Atkinson then lifted his foot up above his head and he felt a number of heavy blows.
The victim required hospital treatment for cuts and bruising to the head and face.
Jenny Haigh, prosecuting, told the court Atkinson had also breached four non-molestation orders and two restraining orders around the time of the attack in April.
The court heard that on one occasion Atkinson contacted his ex partner - the mother of his child, who had a non-molestation order against him - 43 times in five hours.
He also breached a restraining order against his uncle by turning up at the home of his grandmother, who suffers from dementia, while he was there.
The court heard how he was under the influence of drink or a substance and kicked the door after being asked to leave six times.
Atkinson admitted breaching the non-molestation and restraining orders but initially denied the assault occasioning actual bodily harm on his ex-partner's father.
It was not until his former girlfriend and her father arrived to give evidence on the day of the trial last month that Atkinson changed his plea to guilty.
Barry Robson, defending, said: "The difficulty he's had all his life is alcohol."
Mr Robson told the court how Atkinson had been taking part in a 12 step alcohol programme while remanded in custody.
He added: "He's made fantastic steps in regards to the alcohol abuse."
The court heard Atkinson has 22 convictions for 47 offences dating back 13 years.
Recorder Andrew Sutcliffe QC, jailing Atkinson for 18 months, told him: "You appeared before the victim at his home not having seen him since around the time your child was born.
"You knocked on his front door, went into his house and swung two punches at him. This man is disabled and not in a strong condition.
"It was clearly, for him, a most appalling incident.
"The fact it took place while under the influence of drink isn't an excuse for this intolerable behaviour."
Atkinson was handed indefinite restraining orders and exclusion orders against his ex partner and her father.
He was also ordered to abide by unlimited restraining orders against his uncle and his mother.
