A father laughed at his mentally disabled daughter after his ex's new boyfriend tied her up with chains when she suffered a sensory overload episode.
The 43-year-old Illawarra man, who isn't named to protect the identity of his daughter, pleaded guilty in the Wollongong Local Court on Wednesday to assault and intimidation charges over the December 2018 incident.
The girl had scratched her sister and her mother's new boyfriend during the medical episode triggered by loud noises on television, which prompted the man to fetch a long chain, the court heard.
The new boyfriend tied the chains around the 15-year-old's wrist and secured them with a padlock, before her father came into the room and started laughing at her.
