Police have charged a 47-year-old man over the attempted murder of his elderly parents.
An 83-year-old woman and an 83-year-old man were assaulted in their home near Wollongong, south of Sydney, yesterday.
Police arrived at the property in Mount Pleasant to find the woman unconscious with serious head injuries and her husband with head and leg injuries.
The pair were taken to Wollongong Hospital, where the woman remains in a critical condition.
It was there that police arrested the couple's son.
He is alleged to have assaulted two police officers before being taken into custody.
The man has been refused bail and is expected to face court later today.
