A 65-year-old man was hit several times with a broom and knocked unconscious after he told Sean John Wonnacott to slow down in Belvedere Caravan Park.
Wonnacott pleaded guilty to unlawful assault and thereby did bodily harm with circumstances of aggravation when he appeared in Mandurah Magistrates Court.
Police prosecutor Tamara Read said Wonnacott was driving a four-wheel-drive in the caravan park on October 27 and the victim told him to slow down.
Wonnacott got out of his vehicle.
She said the victim pulled out a broom to stop others from fighting and Wonnacott took the broom.
Wonnacott hit the 65-year-old victim several times with the broom, causing him to fall to the ground and lose consciousness for a few seconds.
The victim sustained breaks to the skin and pain to his reconstructed shoulder. The victim was taken to Peel Health Campus to treat a blow to the head.
Wonnacott said he was remorseful over the incident.
“It was a mistake,” he said.
“I just snapped and I am sorry.
“I accept responsibility.
“I was caught up in something and was trying to break it up.”
Wonnacott was sentenced to eight months imprisonment, suspended for 12 months. He must take part in program and supervision requirements.
