AN angry dad fuming over his daughter's ex-boyfriend grabbed a big knife and electric cable and stormed into the young man's family home.
"Where is your son. I'm going to f***ing kill him," John Jason Bartle told the man's scared mother, Gladstone Magistrates Court heard.
Police prosecutor Snr Const Sam Pyke said Bartle walked up stairs toward the mother with the knife raised then went down a hallway yelling "where is *****", opening doors and looking in, and hitting the wall with the cable.
Snr Const Pyke said two girls were in one bedroom when Bartle waved the knife toward them, demanding to know where the man was.
Bartle walked back past the mother with the knife raised and put the knife blade close to the neck of the family dog sitting on the stairs.
"Please don't kill my dog," the mother called out.
Snr Const Pyke said Bartle then drove straight to Gladstone police station and told officers what he had done.
"He says he only took the knife to scare the ex-boyfriend. He did not intend to use it," Snr Const Pyke said.
Bartle, 61, pleaded guilty to entering a dwelling house when armed with a knife at 8.30pm on June 26, threatening violence, and wilful damage to a railing.
Defence lawyer Cassandra Ditchfield said Bartle's daughter had been in a volatile relationship and went to her father in tears, alleging her ex was saying horrible things on Facebook.
"He had absolutely no intention of causing any harm. He realises it was not the appropriate thing to do and alcohol played a part," Ms Ditchfield said.
Magistrate Mark Morrow said Bartle had lost self-control and warned him "you cannot do that again".
Bartle, who had no prior criminal record was fined $1000 and placed on a 15-month Probation Order with no conviction recorded.
He must pay $555 compensation for the damaged railing.
