A son attacked his mother and smashed up her house and car during a Christmas visit, a court heard.
Ian Wall also threatened to kill mum Val during the rampage at her Bristol home on December 27.
The 44-year-old told her: “I really want to f***ing kill you.
“I wish I stabbed you when I had a chance, when I was younger.”
Wall, who gave his address as Severn Bank Avenue, Lydney, pleaded guilty to damaging property and assault, the Bristol Post reported .
Magistrates ordered a pre-sentence report and committed the case to Bristol Crown Court for sentence on January 26.
He was given bail on condition he live at the Lydney address and have no contact whatsoever with his mother.
Andrew Escott-Watson, prosecuting, said Wall arrived at his mum’s home, in Gallivan Close, Little Stoke, and accused her of talking to him nastily on the phone.
An argument based on money ensued, the court heard, before Wall fetched a mallet and declared: “I’m going to damage the car.”
Mr Escott-Watson said: “He went off and Mrs Wall heard smashing. She called police. The defendant went into the kitchen, knocked the phone out of her hand and hit it twice with the mallet.
“The defendant shoved her in the chest and she fell back and landed in a heap.
“The defendant told her: ‘Stop being such a drama queen’.”
With that Wall hit a cupboard and smashed wine in a rack, magistrates were told. Mrs Wall went upstairs to call police and her son followed and smashed an alarm clock.
They then returned downstairs and Wall repeated that he was going to damage her car.
Mr Escott-Watson said: “She heard the car being smashed. The defendant appeared and told her: ‘I really want to f***ing kill you. I wish I stabbed you when I had a chance, when I was younger.'”
When police arrived Wall said his mum owed money and told them: “I hate coppers.”
Maxine Twinan, defending, said: “Inevitably it’s going to the crown court. He is devastated about the offences.
“He has been struggling with his mental health for some time. He has had a fractious relationship with his mother since he was a child. He is desperate for help.”
