A man who allegedly attempted to strangle an 84-year-old woman after breaking into her north Sydney retirement home and robbing her will remain behind bars until at least February.
The great-grandmother, identified by police as Patricia, allegedly came face-to-face with Peter Thai Vinh Phu Bui when she returned to her room at the North Turramurra facility on November 16.
Bui allegedly attempted to choke her to death and left her with injuries including a fractured nose, bleeding on her brain and cuts to her face, chest and arm.
Police say the 43-year-old Orange man also stole two of Patricia's gold rings.
Bui was on Wednesday arrested in Wahroonga while police raided properties in Pyrmont and Orange, seizing clothing and jewellery.
He has been charged with attempted murder, aggravated break and enter and dealing with proceeds of crime, among other offences.
Police also allege the day before the North Turramurra incident, Bui broke into a Cromer retirement village unit while the occupant was home.
Bui on Thursday did not appear before Hornsby Local Court but was represented by his lawyer. He did not apply for bail and it was formally refused by magistrate Bruce Williams.
He is scheduled to return to court on February 5.
Patricia's daughter Caroline after the alleged assault said her mother "doesn't want to be in this world anymore" because she felt so unsafe.
Caroline said her mother - an "eloquent, proud, wonderful human being" - was also recently widowed, with her husband dying in April.
Patricia, who had moved into the retirement home six weeks before she was attacked, is undergoing rehabilitation.
