A drunken young man with a history of violence repeatedly punched his half-sister in the face before slicing a man with a pizza cutter.
Ryan Gilliatt, 27, launched his violent attack when his half-sister arrived home to find him in her house, and told him to leave, Grimsby Live reported.
When she attempted to escape his repeated punches by running out of the house, a man tried to intervene, aggressively approaching Gilliat, only to be sliced with a pizza cutter and left covered in blood.
Grimsby Crown Court heard it was a prolonged and unprovoked attack which left his victims with "deeply unpleasant" injuries.
Gilliatt, of Grimsby, admitted two offences of assault, causing actual bodily harm, on June 16.
Craig Lowe, prosecuting, told Grimsby Crown Court that Gilliatt's half-sister returned home after a night out to find that he had let himself into her home and was lying on the floor.
"She told him immediately to leave but he ignored her," said Mr Lowe.
She tried to pull him onto a sofa but a "switch seemed to flick" inside him and he stood up and started shouting at her.
"He punched her to the face on a number of occasions," said Mr Lowe.
Most of the blows landed, with Gilliatt sitting on top of the woman "raining punches down on [her] face" but she managed to get him off and run out of the back door, shouting for help.
A man came to her assistance, saw a lump on her forehead and eye injuries, and noticed that she was crying.
She told him: "Ryan's battered the f*** out of me."
Gilliatt aggressively approached the man, who pushed him, causing Gilliatt to fall to the ground.
He got up and returned to his half-sister's home before returning with a pizza cutter taken from her kitchen.
He swung the pizza cutter at the man, slicing his left arm and back and leaving his back with a three-inch cut, covered in blood.
The man punched him on the jaw in self-defence, causing him to drop the cutter, which the man picked up.
But Gilliatt returned with a broken sweeping broom and tried to swing it at the man's head.
He punched Gilliatt in the face, who fell, before he got up and ran off.
Gilliatt later told police: "I feel bad for what I have done to my sister."
The court heard he had 17 previous convictions, including being locked up in 2013 for three years and two months for two offences of assault, causing actual bodily harm and another of burglary, involving violence.
He had other convictions for burglary, attempted burglary, possessing a blade, assault and affray and had served several prison sentences including one year, 18 months and 16 weeks.
Recorder Adrian Langdale QC told Gilliatt that the injuries he left his victims with her “unpleasant”.
"This was a prolonged, unprovoked, drunken, violent attack against two people.
“You returned with a second weapon, having lost your first,” he said.
"You have a significant history of violence and aggressive behaviour. It seems you don't seem to learn lessons.”
While QC Langdale said the defendant didn’t seem to show remorse, he acknowledged that he did seem to “accept” that he had problems with his temper.
Julia Baggs, mitigating, said they were "deeply unpleasant" injuries and Gilliatt had little memory of the incident because he had been drinking heavily.
"It was an unprovoked piece of violence," said Miss Baggs. "He would like to express his remorse. He is utterly ashamed of his behaviour.
"He has difficulty with his temper. He is quick to anger. He has long-standing drink and drug issues."
Gilliatt was jailed for two years and three months.
