A drunken man ranted: “The Queen will not be happy about this” when police arrested him over his threats to stab youths congregating outside his home.
Walter Usher claimed he had been in the RAF and also name-dropped Huddersfield University chancellor Prince Andrew during the bizarre outburst at his Newsome home.
Kirklees Magistrates ordered him to keep the peace for a year or he risks being fined.
The court heard that police went to the 64-year-old’s Edale Avenue home at just before 6pm on Wednesday.
Tom Penman, prosecuting, said: “There had been issues with children knocking on his windows and police had been called round to deal with the defendant’s reaction to that.
“There were children playing outside and Mr Usher was agitated.
“He was shouting loudly and aggressively, smelt of intoxicants and was unsteady on his feet.
“The defendant started ranting.
“He said he was in the RAF and that the Queen and Prince Andrew would not be happy about what was going on.”
Usher then picked up a knife twice and threatened: “I will kill them, I will stab them.”
His aggressive behaviour continued as he was arrested, the court heard.
In April 2012 Usher was convicted for an offence of assault occasioning actual bodily harm.
He was jailed for 27 months after attacking his elderly neighbour with a zimmer frame.
Usher’s sentence was later cut to 18 months by judges at London’s Appeal Court.
Zahid Majeed, mitigating, said that young people would go to his client’s home, knock on the window and run away.
He explained that this had caused Usher some distress and he had told his support worker who in turn had called police.
Mr Majeed said: “Mr Usher accepts that in his emotional state he’s acted in a manner which has resulted in a breach of the peace.
“He felt there was nothing more he could he could do than express his anger.”
Usher appeared at the court in custody following his arrest over the episode.
Magistrates bound him over to keep the peace for 12 months.
If Usher does not behave himself during this time he will have to pay a fine of £100.
