A man grabbed his partner’s mother round the throat and threatened her with two knives as he was unhappy about her living at their Heacham home, a court heard.
Roger Hutchinson was warned he faces jail after attacking his partner and her mother when he came home drunk from a Christmas work party.
Lynn magistrates also heard that the 44-year-old told his partner and her mother, and the police officers who arrested him, that he would burn all their houses down.
Hutchinson appeared before the court on Friday and admitted assaulting his partner and her mother, causing criminal damage to a door and obstructing a police officer in the execution of his duty on December 21.
Yvonne Neill, prosecuting, said Hutchinson had been at a Christmas work party with his partner at The Lodge in Old Hunstanton, but they had an argument and left separately.
When they arrived home the argument continued and Hutchinson pinned his partner against the wall.
Ms Neill said: “Her mother tried to intervene but he grabbed her round the throat and said ‘I’m not scared of you’.
“He then pushed her into the kitchen and had her arms across her back.”
The partner pulled Hutchinson off her mother and she ran to the bedroom, but he went after her with a bread knife, saying “If I’m going to get done I might as well do the job properly”.
Ms Neill said Hutchinson then left, but returned shortly afterwards and threatened the mum with a paring knife.
She said his partner tried to get the knife off him, and he cut himself in the struggle.
Hutchinson’s partner then called her brother, who came round and apprehended Hutchinson until police arrived.
“The police arrived and the defendant became aggressive towards them. He said he’d return to burn the house down and theirs as well,” said Ms Neill.
Tim Bartlam, for Hutchinson, said: “The issue the defendant has got is that he is upset because the mum is living at the house and had been doing so for five to six weeks.
“He can’t explain how he acted the way he did and expresses considerable remorse.”
Hutchinson, currently living at a bail address in Windmill Green, Bury St Edmunds, was warned he could go to prison for the offence.
The case was adjourned until February 7 for a pre-sentence report to be prepared, and he was released on conditional bail until then.
